Gradient Compensation Torque Control Method, Device and Vehicle

Abstract

The present application discloses a compensating torque control method, device and automobile, wherein the former includes acquiring current slope information and judging whether the current slope information is 0. When the current gradient information is not 0, the first torque curve is used to compensate the first torque according to the current gradient information; the first torque curve is a curve for determining the required compensation torque according to the first load and gradient information. When the current gear and the current direction of travel are inconsistent, use the second torque curve to compensate the second torque according to the current slope information; the second torque is greater than the first torque; the second torque curve is determined according to the second load and slope information Curve of compensation torque; the second load is greater than the first load. It can be seen from the above that this application uses two torque curves to perform torque compensation according to different slope information and load conditions, without adding any hardware equipment, and reducing costs. And there is no failure, so its stability is also high.

Description

technical field [0001] The present application relates to the technical field of automobiles, in particular to a slope compensation torque control method, device and automobile. Background technique [0002] As a means of transportation, cars have become more and more mature. With the development of urbanization, the number of cars on the road has also doubled. Traffic jams have become commonplace. If traffic jams occur on uphill and downhill roads, it is very easy to slip. car accidents, resulting in accidents. [0003] In order to solve the situation of the car slipping on the uphill and downhill sections, the current solution is to ensure that the car is idling at a certain speed, and to ensure that the car is idling, it is necessary to increase the slope compensation torque. At present, the way to increase the slope compensation torque is: judge the load according to the load sensor, and then determine the compensation torque required on the uphill and downhill sections...

AI Technical Summary

Problems solved by technology

[0004] However, the method of using the load sensor to judge the load is relatively high in cost and increases the burden on the vehicle network

In addition, there is a risk that when the load sensor fails, the load condition of the car cannot be recognized normally
