Description

Helmet, rider assistance system, and control method thereof

Technical Field

The present invention relates to a helmet fitted to a head of a rider, a rider assistance system including the helmet, a control method of the helmet, and a control method of the rider assistance system.

Background

As conventional rider assistance systems, the following systems are known: a motion control device incorporated in a straddle-type vehicle automatically decelerates or automatically accelerates the straddle-type vehicle in accordance with surrounding environment information acquired during traveling, without depending on the operation of a rider (for example, patent document 1).

Patent document 1: international publication No. 2018/185577.

The automatic deceleration or the automatic acceleration suddenly occurs, so the following easily occurs: the rider is confused about the automatic deceleration or the automatic acceleration, and the riding vehicle on which the rider rides becomes unstable in traveling. In particular, in a straddle-type vehicle, traveling stability is easily impaired as compared with other vehicles (e.g., an automobile, a truck, and the like), and therefore, it is necessary to appropriately deal with automatic deceleration or automatic acceleration by a rider. Therefore, in the conventional rider assistance system, when the automatic deceleration or the automatic acceleration occurs, a warning operation for notifying the rider of the automatic deceleration or the automatic acceleration is executed. The warning operation is executed by issuing a warning by a device incorporated in the vicinity of the handlebar of the saddle-ride type vehicle on which the rider rides. However, in a situation where the rider notices a direction different from the proceeding direction, it is difficult for the rider to recognize the warning issued from the apparatus, and processing with respect to automatic deceleration or automatic acceleration becomes difficult.

< Structure of rider assistance System >

The structure of the rider assistance system of the embodiment will be explained.

Fig. 1 is a diagram for explaining a schematic configuration of a rider assistance system according to an embodiment of the present invention. Fig. 2 is a diagram showing a system configuration of the rider assistance system of the embodiment of the present invention.

As shown in fig. 1 and 2, the rider assistance system 100 includes at least a behavior control device 10, a brake device 20, a drive device 30, and a communication device 50 incorporated in the straddle-type vehicle 1, and a helmet 80 attached to the head of the rider.

Detection results of various sensors mounted on the straddle-type vehicle 1 are input to the motion control device 10. The behavior control device 10 causes the straddle-type vehicle 1 to automatically decelerate or automatically accelerate in accordance with the ambient environment information acquired during traveling, without depending on the operation of the rider riding the straddle-type vehicle 1. For example, when determining that the predetermined deceleration needs to be generated based on the surrounding environment information, the behavior control device 10 outputs a control command to the brake device 20 or the drive device 30 to cause the straddle-type vehicle 1 to generate the automatic deceleration. When determining that a predetermined acceleration needs to be generated based on the surrounding environment information, the behavior control device 10 outputs a control command to the drive device 30 or the brake device 20 to cause the straddle-type vehicle 1 to generate automatic acceleration.

The respective parts of the motion control device 10 may be provided in a single case in an integrated manner, or may be provided in a plurality of cases separately. A part or the whole of the action control device 10 may be constituted by, for example, a personal computer, a microprocessor unit, or the like, may be constituted by a configuration that can be updated such as firmware, or may be a program module or the like that is executed in accordance with a command from a central processing unit or the like.

The ambient environment information is acquired based on, for example, an output of the ambient environment detection device 40 incorporated in the straddle-type vehicle 1. The surrounding environment detection device 40 is, for example, a radar, a laser sensor, an ultrasonic sensor, a camera, or the like. The surrounding environment detection device 40 may be one or more. The detection range of the surrounding environment detection device 40 may be directed forward of the straddle-type vehicle 1, may be directed rearward of the straddle-type vehicle 1, may be directed to the side of the straddle-type vehicle 1, or may be a combination thereof. The ambient information may be obtained based on the output of the communication device 50 instead of or in addition to the output of the ambient detection device 40. The communication device 50 wirelessly communicates with other vehicles located in the vicinity of the infrastructure or the straddle-type vehicle 1 directly or indirectly.

As an example, the behavior control device 10 executes a collision avoidance operation of the straddle-type vehicle 1. The behavior control device 10 acquires the surrounding environment information based on the output of the surrounding environment detection device 40 or the communication device 50, and determines the possibility of collision of the straddle-type vehicle 1 with respect to objects (a vehicle, a person, an animal, an obstacle, a falling object, and the like) located around (front, rear, lateral, and the like) the straddle-type vehicle 1. When it is determined that the possibility of collision is high, the behavior control device 10 causes the straddle-type vehicle 1 to perform automatic deceleration or automatic acceleration, thereby avoiding the collision.

As an example, the behavior control device 10 executes an adaptive cruise operation of the straddle-type vehicle 1. In the adaptive cruise operation, when there is no preceding vehicle, the straddle-type vehicle 1 is controlled to travel at a target speed set by the rider, and when there is a preceding vehicle, the straddle-type vehicle 1 is controlled to travel at a speed equal to or lower than the target speed and aimed at maintaining the vehicle-to-vehicle distance from the preceding vehicle. The behavior control device 10 acquires the surrounding environment information based on the output of the surrounding environment detection device 40 or the communication device 50, and determines the inter-vehicle distance between the straddle-type vehicle 1 and the preceding vehicle. The action control device 10 causes the straddle-type vehicle 1 to automatically decelerate when determining that the vehicle-to-vehicle distance is short, and causes the straddle-type vehicle 1 to automatically accelerate when determining that the vehicle-to-vehicle distance is long.

As an example, the behavior control device 10 executes an overtaking travel assisting operation of the straddle-type vehicle 1. The behavior control device 10 acquires the surrounding environment information based on the output of the surrounding environment detection device 40 or the communication device 50, and determines the safety of the overtaking travel of the straddle-type vehicle 1 and the presence or absence of the overtaking travel of the rider. When it is determined that the safety is high and the overtaking travel is intended, the behavior control device 10 causes the straddle-type vehicle 1 to automatically accelerate to assist the overtaking travel.

As an example, the action control device 10 executes an inter-vehicle group insertion assisting action of the straddle-type vehicle 1. The behavior control device 10 acquires the surrounding environment information based on the output of the surrounding environment detection device 40 or the communication device 50, and determines whether or not the straddle-type vehicle 1 is in a state of inter-vehicle group intervening travel. When it is determined that the straddle-type vehicle 1 is in a state of inter-vehicle group intervehicular travel, the action control device 10 automatically decelerates the straddle-type vehicle 1 to assist the inter-vehicle group intervehicular travel.

The helmet 80 includes at least a communication unit 81 that receives information transmitted from the communication device 50, and a control unit 82 that executes a warning operation with respect to a rider to which the helmet 80 is attached, based on the information received by the communication unit 81. The communication unit 81 automatically starts communication with the communication device 50 when the main power supply of the helmet 80 is turned on. The communication unit 81 may directly receive information transmitted from the communication device 50, or may indirectly receive information via the mobile wireless terminal 90 (a smartphone, a tablet computer, or the like). The control unit 82 may execute the warning operation by causing the sound output unit 83 provided in the helmet 80 to output a warning, may execute the warning operation by causing the display unit 84 provided in the helmet 80 to output a warning, or may execute both of them. The sound output unit 83 may output a sound indicating a warning, may output a warning message, or both. The sound output unit 84 may turn on a lamp indicating a warning, may display a warning message, or both.

The controller 82 may be provided in a single case in an integrated manner, or may be provided separately in a plurality of cases. A part or all of the control unit 82 may be constituted by, for example, a personal computer, a microprocessor unit, or the like, may be constituted by a configuration that can be updated such as firmware, or may be a program module or the like that is executed in accordance with an instruction from a central processing unit or the like.

The communication unit 81 receives behavior control information, which is information for causing the straddle-type vehicle 1 to automatically decelerate or automatically accelerate in accordance with the surrounding environment information acquired while the behavior control device 10 is traveling. The control unit 82 executes a warning operation based on the action control information received by the communication unit 81. The control unit 82 may execute a warning operation for warning only the presence or absence of the automatic deceleration or the automatic acceleration, or may execute a warning operation for warning the magnitude of the warning operation in addition to the presence or absence of the automatic deceleration or the automatic acceleration.

< actions of rider assistance System >

The operation of the rider assistance system of the embodiment will be described.

Fig. 3 is a diagram illustrating an example of the operation flow of the rider assistance system according to the embodiment of the present invention.

While the straddle-type vehicle 1 is traveling, the operation flow shown in fig. 3 is repeatedly executed.

(determination step)

In step S101, the behavior control device 10 incorporated in the straddle-type vehicle 1 acquires the surrounding environment information and determines whether or not it is necessary to cause the straddle-type vehicle 1 to automatically decelerate or automatically accelerate. If it is necessary to cause the straddle-type vehicle 1 to perform the automatic deceleration or the automatic acceleration, the process proceeds to step S102, and if not, step S101 is repeated.

(communication step)

In step S102, the communication unit 81 of the helmet 80 directly or indirectly receives the behavior control information, which is information for the automatic deceleration or the automatic acceleration that the behavior control device 10 generates in the straddle-type vehicle 1, from the communication device 50 incorporated in the straddle-type vehicle 1.

(control step)

In step S103, the control unit 82 of the helmet 80 performs a warning action with respect to the rider based on the action control information received in step S102.

(action control step)

In step S104, the action control device 10 causes the straddle-type vehicle 1 to perform automatic deceleration or automatic acceleration.

The order of the steps may be changed as appropriate, and further steps may be added as appropriate. For example, step S103 may be executed after the start of step S104, or may be executed before and after the start of step S104.

< Effect of rider assistance System >

Effects of the rider assistance system of the embodiment will be described.

In the rider assistance system 100, the helmet 80 attached to the head of the rider includes a communication unit 81 and a control unit 82, the communication unit 81 directly or indirectly receives information transmitted from the communication device 50 incorporated in the straddle-type vehicle 1, the control unit 82 performs a warning operation for the rider based on the information received by the communication unit 81, the communication unit 81 receives, as information, action control information that is information for automatically decelerating or automatically accelerating the straddle-type vehicle 1 in accordance with surrounding environment information acquired during travel by the action control device 10 incorporated in the straddle-type vehicle 1, and the control unit 82 performs the warning operation based on the action control information received by the communication unit 81. Therefore, even in a situation where the rider notices a direction different from the proceeding direction, the warning is easily recognized, and the processing for the automatic deceleration or the automatic acceleration becomes easy.

The embodiments of the present invention are not limited to the above description. That is, the present invention includes a mode in which a deformation is applied to the above-described embodiment. That is, the present invention includes a mode in which only a part of the above-described embodiments is implemented or a mode in which these modes are combined with each other.

Fig. 4 is a diagram for explaining a schematic configuration of a modification of the rider assistance system according to the embodiment of the present invention.

For example, although the above description has been made on the case where the communication unit 81 of the helmet 80 receives the behavior control information of the straddle-type vehicle 1 on which the rider who mounts the helmet 80 mounts, alternatively or additionally, as shown in fig. 4, the communication unit 81 of the helmet 80 may receive the behavior control information of the straddle-type vehicle 1 on which the rider who mounts the helmet 80 does not mount. That is, the control unit 82 of the helmet 80 may notify the rider of the automatic deceleration or the automatic acceleration that occurs in the straddle-type vehicle 1 on which the rider fitted the helmet 80 is not riding. The straddle-type vehicle 1 may be a leading vehicle of a straddle-type vehicle 101 on which a rider equipped with a helmet 80 rides. With such a configuration, processing for automatic deceleration or automatic acceleration occurring in a preceding vehicle becomes easier. Further, the straddle-type vehicle 101 may be capable of generating automatic deceleration or automatic acceleration, or may not be capable of generating automatic deceleration or automatic acceleration. The straddle-type vehicle 1 and the straddle-type vehicle 101 may be vehicles that are set to travel collectively in the same group. When the vehicle travels collectively, the necessity of decelerating or accelerating the straddle-type vehicle 101 in conjunction with automatic deceleration or automatic acceleration of the straddle-type vehicle 1 increases. That is, the configuration in which the control portion 82 notifies the rider of the automatic deceleration or the automatic acceleration generated by the straddle-type vehicle 1 on which the rider fitted with the helmet 80 does not ride is particularly useful in collective traveling.
