Coordination control method simulating automobile braking

Abstract

The invention discloses a coordination control method simulating automobile braking and belongs to the technical field of automobile braking control. The method includes the steps that based on the obtained pedal travel, the total braking torque is calculated; based on the obtained flywheel rotating speed, current signal, voltage signal and pedal travel, the total braking torque is distributed, the electronic control hydraulic braking torque and the motor braking torque are obtained; an electronic control hydraulic controller forms braking pressure based on the received electronic control hydraulic braking torque and outputs the braking pressure to a disc brake, and then braking control over a flywheel is conducted; a motor controller forms a target rotation speed signal based on the received motor braking torque and sends the target rotation speed signal to a motor; and the motor carries out braking control over the flywheel based on the received target rotation speed signal. The coordination control method simulating automobile braking can be used for realizing coordination control over an automobile.

Description

technical field [0001] The invention relates to the technical field of automobile braking control, in particular to a coordinated control method for simulating automobile braking. Background technique [0002] At present, energy shortage and environmental pollution are serious problems faced by countries all over the world. According to the current speed of use, the oil on the earth can only last for about 40 years, that is to say, the traditional cars that use cheap oil as the power source will inevitably be eliminated in the future. universal. In order to improve energy utilization efficiency, current engineers and technicians are devoted to the research of hybrid electric vehicle regenerative braking energy recovery technology. [0003] At present, scholars at home and abroad have conducted a lot of research on hybrid electric vehicle regenerative braking energy recovery and brake-by-wire technology, and proposed a variety of regenerative braking and hydraulic braking m...

Problems solved by technology

[0004] However, in the prior art, the driver usually starts or stops coasting energy feedback charging manually, which does not reflect the situation of regenerative braking and conventional hydraulic braking, resulting in that the braking torque depends on the vehicle speed and the SOC state of the battery, and the operation is cumbersome. Embodies the regenerative braking function, the feedback energy is small and the switching transition fluctuates greatly
