Embodiment Construction

[0076] Such as figure 1 As shown, the speed measurement method of the multi-axis independent wheel drive vehicle of the present invention comprises:

[0077] Step 100: Collecting the speed signal and torque signal of each wheel while collecting the acceleration state of the vehicle in real time.

[0078] Step 200: Adjust the torque signals of some wheels according to the slip ratio of the wheels and form the actual vehicle speed of the vehicle according to the rotational speed signals of some wheels.

[0079] The method for measuring and calculating the vehicle speed of a multi-axis independent wheel drive vehicle of the present invention provides a method for controlling and measuring the actual vehicle speed of a multi-axis independently driven electric vehicle under the condition that multiple wheels slip or lock simultaneously. The calculation method is based on the vehicle The minimum interference of driving / braking force can not only ensure the driving stability and bra...

Abstract

The invention solves the technical problem that the actual vehicle speed measurement and calculation error is large when the wheels rotate abnormally during the independent control process of the wheels. Includes collecting rotational speed signal and torque signal of each wheel at the same time of real-time collecting acceleration state of vehicle; The torque signal of the partial wheels is adjusted according to the slip rate of the wheels and the actual vehicle speed of the vehicle is formed according to the rotational speed signal of the partial wheels. A method for control and measuring that actual vehicle speed of a multi-axle independently driven electric vehicle unde the condition that a plurality of wheels are slipped or locked at the same time is provide, Based on the minimum interference of vehicle driving / braking force, this method can not only ensure the vehicle running stability and braking safety, but also calculate the actual vehicle speed, which provides the key parameter information for the vehicle dynamic driving. The method and device are applicable to multi-axle dependent vehicles with anti-lock braking systems and to all electrically driven multi-axle vehicleswith independent wheelside drive.

Description

[0001] The present invention is proposed by the applicant, the application date is May 30, 2018, the application number is 2018105365344, and the priority of the application titled "a method and device for measuring and calculating the speed of a multi-axis independent wheel drive vehicle" . The entire content of the above application is hereby incorporated by reference in its entirety. technical field [0002] The invention relates to a method and device for measuring and calculating vehicle speed, in particular to a method and device for measuring and calculating the vehicle speed of a multi-axle independent wheel drive vehicle. Background technique [0003] Multi-axle independent wheel drive vehicles drive the wheels directly by motors or integrate the motors and wheels in the form of hub motors. This driving form makes the drive system of multi-axle heavy vehicles more efficient, more flexible in control, and contributes to dynamic safety. Performance improvements and e...
