Abstract

The invention relates to the technical field of vehicle control, and provides a vehicle ramp crawling control method and a vehicle. The vehicle ramp crawling control method comprises the steps of determining the gradient of a ramp on which the vehicle is driving; determining a compensation torque corresponding to the gradient, wherein the compensation torque and the gradient are in a positive correlation relationship; and outputting the compensation torque to compensate the driving torque to the expected torque, and wherein under the action of the expected torque, the vehicle can travel on ramp with the gradient according to the target creeping speed. Therefore, by means of the vehicle ramp crawling control method, the crawling function of the vehicle can be well achieved on the road surfaces with various gradients, and the crawling driving safety and driving comfort of the vehicle are improved.

Description

technical field [0001] The invention relates to the technical field of vehicle control, in particular to a vehicle ramp creep control method and a vehicle. Background technique [0002] Today's car ownership has increased exponentially, and the progress of road infrastructure has obviously lagged behind the growth rate of cars. As a result, traffic congestion has become the norm for a period of time in the future. The vehicle's creeping function saves drivers from frequently operation, liberate the driver's feet, reduce fatigue and increase driving comfort. [0003] In the related art, in order to realize the creep function of the vehicle, generally vehicle manufacturers will control the vehicle (especially pure electric vehicles) to output a torque corresponding to the target creep speed to realize the creep function. [0004] However, the inventors of the present application found that in the process of practicing the present application, there are at least the following ...
