Specifically, fig. 1 is a schematic flow chart of a method for preventing a gear shift error of a vehicle according to an embodiment of the present application.
As shown in fig. 1, the gear error prevention method of the vehicle includes the steps of:
in step S101, an intended shift position of the vehicle is detected.
It can be understood that the intended gear may be a forward gear or a reverse gear, and the intended gear may be determined according to the gear engaged by the user in the embodiment of the present application.
Optionally, in some embodiments, before detecting the intended gear of the vehicle, comprising: judging whether the vehicle is powered on; and if the vehicle is powered on, acquiring the distance between the vehicle and the front obstacle and/or the distance between the vehicle and the rear obstacle.
It should be understood that some relevant driving operations can be performed after the vehicle is powered on, and therefore, in the embodiment of the present application, before detecting the intended gear of the vehicle, it may be determined whether the vehicle is powered on, and after the vehicle is powered on, the distance between the vehicle and the front obstacle, the distance between the vehicle and the rear obstacle, or the distance between the vehicle and the front obstacle and the distance between the vehicle and the rear obstacle are acquired at the same time by using the ultrasonic sensor.
The obstacle may be a person or an animal, or may be a wall, and is not particularly limited herein. In step S102, when the intended shift position is the forward shift position, it is determined whether a distance between the vehicle and the front obstacle is smaller than a first preset safety threshold, and when the intended shift position is the reverse shift position, it is determined whether a distance between the vehicle and the rear obstacle is smaller than a second preset safety threshold.
The first preset safety threshold and the second preset safety threshold may be thresholds preset by a user, may be thresholds obtained through limited experiments, or may be thresholds obtained through limited computer simulation.
It can be understood that, when the intended gear is a forward gear, the embodiment of the present application may calculate, by using a VCU (Vehicle control unit ), a distance between the Vehicle and a front obstacle, which is acquired by an ultrasonic sensor, and determine a size of the distance and a first preset safety threshold; when the intention gear is a reverse gear, the distance between the vehicle and the rear obstacle collected by the ultrasonic sensor can be calculated through the VCU, and the distance and the second preset safety threshold value are judged.
In step S103, if the distance to the front obstacle is smaller than a first preset safety threshold or the distance to the rear obstacle is smaller than a second preset safety threshold, a gear shift confirmation instruction is sent, and after a confirmation instruction fed back by the gear shift confirmation instruction is received, the vehicle is controlled to engage in the intended gear.
It can be understood that if the distance between the vehicle and the front obstacle is smaller than a first preset safety threshold, or the distance between the vehicle and the rear obstacle is smaller than a second preset safety threshold, which indicates that a danger exists, in the embodiment of the present application, a gear confirmation instruction may be sent, for example, a central control large screen or an IHU (information Head Unit) may prompt the driver that the front obstacle is too close, whether to continue to engage in the forward gear, or the reverse gear, and after the user confirms the gear, the vehicle is controlled to engage in the forward gear or the reverse gear.
Optionally, in some embodiments, controlling the vehicle to engage the intended gear comprises: sending a countdown signal within a preset time length; and within the preset time, receiving a cancel instruction, stopping engaging the intended gear, and otherwise, controlling the vehicle to engage the intended gear after the preset time.
It can be understood that a preset time is set in the embodiment of the application, if a user receives a gear canceling instruction of the user within the preset time, the user stops to engage the intended gear, and if the user does not send an instruction within the preset time, the vehicle engages the intended gear, so that intelligent control of the vehicle is further achieved, and the situation that the vehicle is not controlled to engage the intended gear because the user does not receive a confirmation instruction all the time is avoided.
Optionally, in some embodiments, the above method for preventing gear shift of a vehicle from error further includes: and if the distance between the vehicle and the front obstacle is greater than or equal to a first preset safety threshold value or the distance between the vehicle and the rear obstacle is greater than or less than a second preset safety threshold value, controlling the vehicle to be in the intended gear.
It can be understood that if the distance between the vehicle and the front obstacle is greater than a first preset safety threshold or the distance between the vehicle and the rear obstacle is greater than a second preset safety threshold, it indicates that there is no danger of collision whether the vehicle is moving forward or backward, and the vehicle can be controlled to be in a forward gear or a backward gear.
Optionally, in some embodiments, after controlling the vehicle to engage the intended gear, further comprising: generating a reminding signal according to the actual distance between the reminding signal and the front obstacle or the actual distance between the reminding signal and the rear obstacle; and controlling a reminding device to remind according to the reminding signal until the target gear is exited or the actual distance is greater than or equal to the corresponding preset safety threshold.
It will be appreciated that, when the vehicle is in the forward gear, as the vehicle advances, the distance between the vehicle and the obstacle in front will decrease, therefore, in order to further improve the safety, the embodiment of the application can always calculate the actual distance between the vehicle and the front obstacle, and generates a reminding signal according to the actual distance between the front obstacles and the actual distance between the front obstacles, for example, when the distance from the front obstacle is more than 1 meter and less than 2 meters, the sound of 'drop', 'drip' is emitted, when the distance between the front obstacle and the front obstacle is more than 0.5 meter and less than 1 meter, the sound of 'dripping', 'dripping' and 'dripping' is emitted, when the distance from the front obstacle is less than 0.5 m, the sound of ' dripping ', the ' dripping ' and ' the ' dripping ' is emitted, and along with the reduction of distance, remind the sound more frequently to realize the warning to the user, improve the security.
It should be noted that, after the vehicle is engaged in the reverse gear, as the vehicle moves backward, the distance between the vehicle and the rear obstacle is smaller and smaller, and the control method is the same as the above-mentioned method for engaging in the forward gear, and details are not described here to avoid redundancy.
In order to enable those skilled in the art to further understand the gear error-proofing method of the vehicle according to the embodiment of the present application, the following detailed description is provided with reference to specific embodiments.
As shown in fig. 2, the gear error prevention method of the vehicle includes the steps of:
and S201, electrifying the whole vehicle.
S202, the ultrasonic sensor detects the distance between the front obstacle and the rear obstacle of the vehicle, and the ultrasonic controller sends a distance signal to the VCU.
S203, the VCU judges whether the distance of the obstacle is within the safe distance, if so, the step S204 is executed, otherwise, the step S205 is executed.
And S204, setting the position of the obstacle mark as 0.
And S205, setting the mark position of the obstacle as 1, and delaying the target gear of the driver.
S206, prompting the driver that the obstacle is too close, judging whether to continue to engage the forward gear or the reverse gear, if so, executing the step S207, otherwise, executing the step S208.
And S207, setting the mark position of the obstacle object to be 0, canceling the target gear delay, and sending out the forward gear or the backward gear of the driver target gear.
And S208, maintaining the target gear to be powered on and initializing the default gear.
Therefore, according to the embodiment of the application, the VCU delays the target gear output of the driver, meanwhile, the warning information is sent to the IHU, the central control screen prompts the driver that a front obstacle is too close, whether the D/R (forward/backward) gear is continuously engaged or not, after the driver clicks to confirm the engagement, the IHU (entertainment information host) sends a driver gear confirmation signal to the VCU, after the VCU receives the driver gear confirmation signal sent by the IHU, the gear delay is cancelled, the obstacle mark position 0 is output, and the target gear signal before the driver is output, so that the real driving intention of the driver is judged and confirmed, and the gear mistaken engagement caused by the condition that the driver operates mistakenly and does not see the instrument gear prompt is prevented, and therefore serious safety accidents are caused.
According to the gear error-proofing method for the vehicle, the intention gear of the vehicle can be detected, whether the distance between the vehicle and the front obstacle is smaller than a first preset safety threshold value or not is judged when the intention gear is a forward gear, whether the distance between the vehicle and the rear obstacle is smaller than a second preset safety threshold value or not is judged when the intention gear is a backward gear, if the distance between the vehicle and the front obstacle is smaller than the first preset safety threshold value or the distance between the vehicle and the rear obstacle is smaller than the second preset safety threshold value, a gear confirmation instruction is sent, and the vehicle is controlled to be in the intention gear after a confirmation instruction fed back by the gear confirmation instruction is received. Therefore, the problem of serious personal or property loss caused by the fact that the driver is hooked into an unexpected gear due to misoperation is solved, driving safety of the driver is guaranteed on the premise that driving experience of the driver is not influenced as much as possible, and driving safety is improved.
