Embodiment

[0055] Such as figure 1As shown, the embodiment of the present invention provides a distributed drive system suitable for leaf spring suspension, including DCU1, motor controller 2, distributed drive axle 3 and HCU valve 4.

[0056] The DCU1 is used to control the two motor controllers 2 and the HCU valve 4 to maintain the stable running of the vehicle body.

[0057] In terms of expansion, DCU mainly plays the role of electronic differential control, drive anti-skid control and body stability control. The main principle is that the DCU recognizes the driver's intention according to the accelerator pedal signal, brake pedal signal, gear position signal, etc., judges the vehicle state through the vehicle speed, wheel speed, vehicle yaw acceleration and other signals, and then combines the driver's intention with the vehicle The state separately controls the two motors of the distributed drive axle and the HCU adjusts the braking force of the brake to make the vehicle run safely...

Abstract

The invention provides a distributed driving system suitable for a leaf spring suspension and relates to the technical field of automobiles. The present invention composes DCU (electronic differential speed controller), motor controller, distributed driving axle and HCU into one system, the left and right motors are controlled independently, and there are more degrees of freedom in vehicle dynamics control, which greatly improves the power of the vehicle control performance. The left and right motors, left and right parking brakes and HCU are respectively controlled by the DCU, resulting in higher control efficiency, faster response time, better and more efficient realization of ASR (drive anti-slip), body stability control, intelligent braking and other functions. Improve the vehicle safety.

Description

technical field [0001] The invention relates to the technical field of automobiles, in particular to a distributed drive system suitable for leaf spring suspension. Background technique [0002] New energy vehicles refer to the use of unconventional vehicle fuels as power sources (or the use of conventional vehicle fuels, the use of new vehicle power devices), integrated vehicle power control and advanced technology in driving, the formation of advanced technical principles, with Automobiles with new technology and new structure. [0003] At present, the existing new energy commercial vehicles on the market, especially minibuses and light trucks, mostly use leaf spring suspension for the rear suspension, and the power system is mostly in the form of central direct drive or central motor plus transmission / reducer, that is, simple The original engine and transmission are replaced by the existing motor, plus the transmission shaft and the traditional rear axle to form a power ...
