Embodiment 1

[0069] figure 1 A schematic diagram of an automobile control process provided by an embodiment of the present invention, the process includes the following steps:

[0070] S101: Receive a gear shift request from a current gear to a required gear.

[0071] The vehicle control method provided by the embodiment of the present invention is applied to a vehicle, and specifically can be applied to a VCU (vehicle control unit) of the vehicle.

[0072] The car may receive a shift request from the current gear to the required gear. If the vehicle controller VCU receives the shift request, it may specifically receive the shift request sent by the shifter.

[0073] S102: If the required gear is the P gear, determine whether the current vehicle speed of the car is not greater than the set P gear lock speed threshold, wherein the P gear lock speed threshold is not 0; if yes, go to S103 ; If not, go to S104.

[0074] The vehicle has a pre-set P gear lock speed threshold, and the P gear l...

Embodiment 2

[0084] On the basis of the above embodiments, in the embodiment of the present invention, if the current gear is the P gear, the method further includes:

[0085] judging whether the brake pedal of the car is depressed;

[0086] If yes, shift the current gear to the required gear.

[0087] If the driver is driving the car in P gear, the shift logic is unreasonable. For example, when the speed is high, the vehicle may have problems such as vibration or impact. , switch the current gear P to the required gear.

[0088] If the current gear in the shift request is the P gear, the car can judge whether its own brake pedal has been stepped on. If so, confirm that the current P gear operation will not cause vibration or shock, and the current gear can be switched to demand stalls.

[0089] Specifically, the car can also judge whether its own brake pedal is stepped on, and whether the speed after being stepped on is lower than a set speed threshold, so as to further ensure ride com...

Embodiment 3

[0092] On the basis of the above embodiments, in the embodiment of the present invention, if the current gear is not the P gear and the required gear is not the P gear, the method further includes:

[0093] Obtain the parameters required for the shift permission state corresponding to the current gear and the required gear, and obtain the current parameter values ​​of the parameters, wherein the parameters include the motor speed, the direction of rotation of the motor, the vehicle speed and whether the at least one of the braking signals;

[0094] According to the current parameter value, it is judged whether the automobile is in the shift permission state corresponding to the current gear and the required gear;

[0095] If yes, shift the current gear to the required gear.

[0096] If the current gear in the shift request received by the car is not the P gear and the required gear is not the P gear, the car needs to judge whether the car is currently in the shifting allowabl...

Abstract

The invention discloses an automobile control method, device and automobile. The method includes: receiving a shift request from a current gear to a required gear; if the required gear is a P gear, judging whether the current speed of the automobile is is not greater than the set P gear lock speed threshold, wherein the P gear lock speed threshold is not 0; if so, switch the current gear to the required gear. In the present invention, when switching from other gears to the P gear, the vehicle speed is not greater than the set P gear locking speed threshold, and it is allowed to switch to the P gear, which relaxes the conditions for entering the P gear to a certain extent, and can ensure that the car is slipping on the slope. It can also be switched to the P file when driving, so as to mount the corresponding gear according to the driver's needs.

Description

technical field [0001] The invention relates to the technical field of automobiles, in particular to an automobile control method, device and automobile. Background technique [0002] With the rapid development of the automobile industry, there are more and more vehicles on the road. Similarly, under the condition of ensuring the safety of the vehicle, the driver can switch the gear of the vehicle as he likes in the process of driving. The goal pursued by car companies. [0003] In the prior art, when the gears are switched, there are some situations that the corresponding gears cannot be engaged according to the driver's demand. For example, when switching from other gears to P gear, that is, when entering P gear, the vehicle must be completely still. Take driving on a slope as an example. If the hand brake or brake fails, the vehicle may slip and cannot be completely stationary. The driver cannot switch to the P gear, resulting in the inability to mount the corresponding...
