Description
Technical Field
The application belongs to the technical field of vehicle control, and particularly relates to a vehicle control method, a vehicle control device, a computer-readable storage medium and a vehicle.
Background
In the process of detecting the switch signal of the brake pedal, when judging whether the switch signal of the brake pedal is in fault, the switch signal of the brake pedal usually needs two brake pedal signals as signal inputs, and whether the switch signal of the brake pedal is in fault is judged according to the consistency of the states of the two switch signals.
Therefore, it is an urgent problem to provide a vehicle control method capable of determining whether a switch signal of a brake pedal is faulty without changing a vehicle route.
Disclosure of Invention
The present invention is directed to solving or improving at least one of the above technical problems.
An object of a first aspect of the invention is to provide a vehicle control method.
A second aspect of the invention is directed to a vehicle control device.
A third aspect of the invention is directed to another vehicle control apparatus.
A fourth aspect of the present invention is directed to a computer-readable storage medium.
A fifth aspect of the invention is directed to a vehicle.
The technical scheme of the first aspect of the invention provides a vehicle control method, which comprises the following steps: the method comprises the steps of obtaining the current speed of a vehicle, and triggering a brake pedal fault detection mechanism after the current speed of the vehicle is larger than or equal to a first speed, wherein the brake pedal fault detection mechanism comprises the following steps: detecting the number of times that a brake pedal switch signal is activated in the process that a brake pedal fault detection mechanism is triggered until the speed of the vehicle is reduced to a second speed; and when the number of activated brake pedal switch signals is less than the preset number, triggering a brake pedal signal fault emergency mechanism.
The invention provides a vehicle control method, which comprises the following steps: when the current speed of the vehicle is larger than or equal to the first speed, starting to trigger a brake pedal fault detection mechanism, wherein the brake pedal fault detection mechanism comprises the steps that in the process from the start of triggering the brake pedal monitoring fault to the reduction of the current speed to the second speed, the number of times of activating a brake pedal switch signal is counted, and when the number of times of activating the brake pedal switch signal is smaller than the set number of times, a brake pedal signal fault emergency mechanism is triggered. Therefore, in the process that the vehicle is reduced from the first speed to the second speed, the phenomenon that the driver can step on the brake pedal is generally considered, if the speed is reduced from the first speed to the second speed, the number of times that the brake pedal switch signal is activated is smaller than the preset number of times, namely the driver does not step on the brake pedal in the process, so that the brake pedal switch signal can have a fault, and at the moment, a brake pedal signal fault emergency mechanism is triggered. The vehicle control method can judge whether the brake pedal switch signal breaks down according to the number of times that the brake pedal switch signal is activated, and solves the problems that the prior art mentions that the failure can be diagnosed only by changing a single-signal brake pedal into a double-signal brake pedal, so that the vehicle wire harness is passively changed, and the cost is increased. Further, the brake pedal fault detection mechanism is triggered only after the current speed of the vehicle is larger than or equal to the first speed, so that when the current speed of the vehicle is reduced from the first speed to the second speed, the default vehicle must have a deceleration process of stepping on the brake, the probability of the driver stepping on the brake pedal is high, and at the moment, the brake pedal fault detection mechanism is started to quickly detect whether the brake pedal switch is in fault.
Wherein the first speed is analyzed based on a large number of practical experiences. Above this speed threshold, the driver must essentially step on the brakes until the vehicle is close to stopping. That is, when the brake is applied at this speed, the vehicle is generally stopped. The second speed is a substantially stopped speed, which is less than the speed at which the vehicle is idling, typically less than 10km/h, and further less than 5km/h, so that when the second speed is sufficiently small, it is ensured that the driver depresses the brake pedal.
In the technical scheme, when the number of times of the brake pedal switch signal activation is greater than or equal to the preset number of times, the brake pedal signal fault emergency mechanism is in a closed state.
In the technical scheme, when the number of times of the brake pedal switch signal being activated is greater than or equal to the preset number of times, it indicates that the brake pedal signal is likely to be frequently triggered, that is, the brake pedal switch signal is in a normal state, and at this time, the brake pedal signal fault emergency mechanism is in a closed state.
The vehicle control method further includes: the brake pedal failure detection mechanism is in an off state when the current speed of the vehicle does not reach the first speed.
In the technical scheme, when the current speed of the vehicle does not reach the first speed, the brake pedal fault detection mechanism is in a closed state, so that the problems that when the speed of the vehicle is low, the brake pedal fault detection mechanism is triggered, data is large, and a memory is frequently replaced can be avoided.
In the above technical solution, the vehicle control method further includes: upon detection of a misfire command, the brake pedal fault detection mechanism is placed in an off state.
In the technical scheme, when a flameout instruction is detected, the brake pedal fault detection mechanism is in a closed state, so that power failure treatment can be timely performed, and the phenomenon that the service life of the device is reduced due to the fact that the device is in a working state for a long time is avoided.
In the technical scheme, as long as the vehicle speed reaches the first speed, the vehicle can continuously monitor the signal state of the brake pedal.
In the technical scheme, the preset times are more than or equal to 1 time and less than or equal to 3 times.
In the technical scheme, the preset times are more than or equal to 1 time and less than or equal to 3 times, preferably 1 time, that is, if the speed is reduced from the first speed to the second speed, and the brake pedal signal is not triggered for 1 time, the brake pedal switch signal is determined to be in fault, so that the detection accuracy can be improved. Of course, the preset times can be 2 times or 3 times, because the habits of different drivers on braking are different, the precision rate can be further improved.
In the above technical solution, the first speed ranges from 60km/h to 100km/h, and the second speed ranges from 0km/h to 20 km/h.
In the technical scheme, the first speed ranges from 50km/h to 120km/h, further ranges from 60km/h to 100km/h, the second speed ranges from 0km/h to 30km/h, and the preferred second speed is 0km/h, so that the accuracy of measurement can be further ensured. Of course, the first speed and the second speed may be changed according to the driving habits of the driver.
In the above technical solution, the step of triggering the brake pedal signal failure emergency mechanism includes: and prompting that the brake pedal switch signal has a fault.
In the technical scheme, the step of triggering the brake pedal signal fault emergency mechanism comprises the step of prompting that a brake pedal switch signal has a fault, so that when the brake pedal switch signal fault is detected, a fault prompt can be sent out, and a driver can maintain the brake pedal switch signal in time.
A second aspect of the present invention provides a vehicle control device, including: the speed acquisition module is used for acquiring the current speed of the vehicle; the control module is used for triggering a brake pedal fault detection mechanism after the current speed of the vehicle is greater than or equal to a first speed, and the brake pedal fault detection mechanism comprises: detecting the number of times that a brake pedal switch signal is activated in the process that a brake pedal fault detection mechanism is triggered until the speed of the vehicle is reduced to a second speed; and when the number of activated times of the brake pedal switch signal is less than the preset number of times, triggering a brake pedal signal fault emergency mechanism.
The vehicle control device comprises a speed acquisition module and a control module, wherein the speed acquisition module is used for acquiring the current speed of a vehicle, and the control module is used for starting to trigger a brake pedal fault detection mechanism after the current speed of the vehicle is greater than or equal to a first speed. The brake pedal failure detection mechanism includes: and detecting the number of times of the activation of the brake pedal switch signal in the process that the vehicle speed is reduced to a second speed from the beginning of triggering the brake pedal fault detection mechanism, and triggering the brake pedal signal fault emergency mechanism when the number of times of the activation of the brake pedal switch signal is less than or equal to the preset number of times.
