Problems solved by technology
However, due to the limited adhesion characteristics of tire longitudinal and lateral coupling, the maximum allowable value of longitudinal acceleration will be affected by lateral acceleration when the vehicle is turning.
In the prior art, the process of setting the steering style does not take into account the lateral acceleration of the vehicle during driving. Therefore, when the user drives the vehicle for high-speed, large-curvature steering manipulation, the driving state of the vehicle will , may not satisfy the user's desired manipulation style

Embodiment approach
[0142] Optionally, in another embodiment of the present application, an implementation manner when the acquiring unit 801 acquires the road condition information of the current location of the vehicle includes:
[0143] The first determining unit is configured to determine the current position of the vehicle according to the current positioning signal of the vehicle.
[0144] The query unit is used to query the road index of the high-precision map to obtain the road index of the current location of the vehicle.
[0145] Among them, the road index of the high-precision map records the adhesion coefficient of the road surface of each segmented road and the curvature information of each reference path point in the reference path; the reference path is formed by sequentially connecting multiple reference path points.
[0146] The reading unit is used to read the adhesion coefficient of the road surface where the vehicle is currently located from the road index of the current vehic...

The invention provides a vehicle control method and device, electronic equipment and a computer storage medium, and the vehicle control method comprises the steps: firstly, obtaining the road condition information of the current position of a vehicle and the current longitudinal speed of the vehicle in real time, wherein the road condition information comprises an adhesion coefficient of a road surface and a road curvature; then, using a manipulation style model for calculating manipulation style interpolation parameters selected by a user, the current longitudinal speed of the vehicle, the adhesion coefficient of the road surface and the road curvature, and obtaining the target longitudinal acceleration limit and the target longitudinal deceleration limit of the vehicle; and finally, according to the target longitudinal acceleration limit and the target longitudinal deceleration limit of the vehicle, adjusting the response of the current vehicle during longitudinal speed change in the driving process, and limiting the impact caused by longitudinal speed change, wherein the longitudinal speed change comprises longitudinal acceleration and longitudinal deceleration. Therefore, when the user operates the vehicle, the purpose that the driving state presented by the vehicle meets the control style of the user is achieved.
Description
technical field [0001] The present application relates to the technical field of vehicle control, in particular to a vehicle control method, device, electronic equipment and computer storage medium. Background technique [0002] With the development of car intelligence, people have higher and higher requirements for the driving experience during driving, and hope that the car will understand itself more and more. Therefore, people will choose the most suitable control mode according to their own control style. [0003] The existing method for setting the handling style is mainly to change the longitudinal acceleration response by calibrating the torque output table of the power system with respect to the opening of the driving / braking pedal at different vehicle speeds; by defining the maximum opening of the driving / braking pedal Rate of change is allowed to limit acceleration shocks. However, due to the adhesion characteristics of tire longitudinal and lateral coupling, the...
