Abstract

The invention discloses a wheel friction coefficient detection method, a detection terminal and a storage medium. The method includes: obtaining vehicle weight, wheel radius and gravitational acceleration; Angular velocity and driven wheel angular velocity; Calculate and store the left slip rate and right slip rate at each sampling moment respectively according to the angular velocity of the left and right sides of the left and right sides collected at each sampling moment and the angular velocity of the driven wheel, and according to Vehicle weight, wheel radius, gravitational acceleration, and engine output torque collected at each sampling time, calculate and store the drive shaft friction coefficient at each sampling time; slip ratio and right slip ratio to get the maximum friction coefficient of the wheel. The invention can obtain the gradient of the ramp without additionally setting a gradient sensor, thereby reducing the manufacturing cost of the vehicle.

Description

technical field [0001] The invention relates to the field of vehicle detection, and in particular, to a wheel friction coefficient detection method, a detection terminal and a computer-readable storage medium. Background technique [0002] At present, most of the detection methods for the friction coefficient of vehicle tires are to set special sensors to measure tire-related parameters and calculate the friction coefficient. However, the need for additional dedicated sensors to measure tire-related parameters will increase the cost of the car, and the maximum friction coefficient of the wheel cannot be estimated. SUMMARY OF THE INVENTION [0003] The main purpose of the present invention is to provide a wheel friction coefficient detection method, a detection terminal and a computer-readable storage medium, which aims to solve the problem that the existing vehicle tire friction coefficient needs to be additionally provided with a special sensor, which will increase the co...
