A coordinated control device for simulating automobile braking

Abstract

The embodiment of the invention discloses a coordination control device for simulating automobile braking. The coordination control device comprises a pedal stroke collecting unit, an electronic control hydraulic braking system, an electric power system, a control system, a flywheel, a disc brake and a collecting unit arranged in the preset position. The control system is used for outputting initial torque and calculating total braking torque based on the pedal displacement change rate and is further used for distributing the total braking torque based on the total braking torque and all collected signals and outputting electronic control hydraulic braking torque and motor braking torque. The electric power system is used for driving a rotating shaft to rotate based on the received initial torque so that the initial speed of automobile braking can be simulated and is used for driving the rotating shaft to rotate based on the motor braking torque so that rotating speed control over the flywheel can be conducted. The electronic control hydraulic braking system is used for receiving the electronic control hydraulic braking torque and controlling the disc brake to brake the flywheel based on the electronic control hydraulic braking torque. According to the coordination control device for simulating automobile braking, coordination control can be conducted on automobile braking based on electronic control hydraulic braking and motor regenerative braking.

Description

technical field [0001] The invention relates to the technical field of automobile braking control, in particular to a coordinated control device 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 motor regenerative braking energy recovery technology. [0003] At present, scholars at home and abroad have conducted a lot of research on hybrid electric motor regenerative braking energy recovery and brake-by-wire technology, and proposed a variety of regenerative braking and hydraulic braking match...

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 braking torque depending on vehicle speed and battery SOC state, cumbersome operation, only It can reflect the function of regenerative braking, the feedback energy is small and the switching transition fluctuation is large
