Problems solved by technology

At present, when the car brakes, the vehicle will nod. When the speed of the car drops to zero, the force acting on the wheels on the ground will decrease rapidly, and the body will recover quickly, causing the driver and passengers to quickly return to their positions and hit the seat, resulting in personnel discomfort

Embodiment Construction

[0014] In order to deepen the understanding of the present invention, the present invention will be further described below in conjunction with examples, which are only used to explain the present invention and do not constitute a limitation to the protection scope of the present invention.

[0015] This embodiment provides a method for improving vehicle braking comfort, including:

[0016] Step 1: Before the vehicle starts to stop, determine the slope of the road surface, the effectiveness of the brakes, the weight of the vehicle, the driving force acting on the wheels, the position of the accelerator pedal, and the stroke of the brake pedal;

[0017] Step 2: Feedback the parameters of step 1, and the vehicle starts to stop;

[0018] Step 3: Apply braking force to the wheels. The braking force is a function of the gradient of the road surface before stopping, the effectiveness of the brakes, the weight of the vehicle, the driving force acting on the wheels, the position of th...

Abstract

The invention provides a method for improving the braking comfort of a vehicle. When the vehicle is about to be stopped, braking force to be applied to wheels is decided according to the slope of theroad surface, the performance of a brake, the weight of the vehicle, driving force applied to the wheels, the position of an accelerator pedal, the stroke or brake pressure of a brake pedal and the gradient of the brake pedal. The braking force is smaller than traditional braking force, so that impact on a driver and passengers is reduced or eliminated. The braking force differs under different conditions. However, the changes of the braking force neither affect the position of the brake pedal nor interfere with normal driving. When the vehicle stops, braking pressure is applied according to the slope of the road surface and the condition of the driver, so that the safe parking of the vehicle is ensured. When the method is adopted, pressure is reduced first and is then increased, so that impact can be eliminated.

Description

technical field [0001] The invention relates to the field of vehicle braking, in particular to a method for improving vehicle braking comfort. Background technique [0002] Cars are an indispensable tool for people's daily transportation. At present, when the car brakes, the vehicle will nod. When the speed of the car drops to zero, the force acting on the wheels on the ground will decrease rapidly, and the body will recover quickly, causing the driver and passengers to quickly return to their positions and hit the seat, resulting in Personnel discomfort. Therefore, it is necessary to reduce or eliminate the impact on the driver and passengers during the braking process of the vehicle. Therefore, it is necessary to solve this problem. Contents of the invention [0003] In order to solve the above problems, the present invention provides a method for improving the braking comfort of a vehicle. When the vehicle is about to stop, according to the gradient of the road surfa...
