Embodiment Construction

[0010] In the electric steering system in the hybrid power system disclosed in the present invention, a torque sensor 20 is arranged on the steering input shaft connected to the steering wheel 10, and the torque sensor 20 collects the steering torque signal and the rotation speed signal and inputs them to the EPS electric steering controller 40, EPS The electric steering controller 40 also receives the vehicle speed signal, and the EPS electric steering controller 40 outputs a control signal to the steering motor 30 installed on the steering shaft, and the steering motor 30 drives the direction of rotation and The size of the rotation.

[0011] It can be seen from FIG. 1 that the steering sensor torque sensor 20 is installed on the steering input shaft and will collect two signals: a steering torque signal and a rotation speed signal. At the same time, the EPS electric steering controller 40 also needs to receive the vehicle speed signal. According to these three signals, the...

Abstract

The present invention relates to an electric turning system in a hybrid system. A turning input shaft connected with a steering wheel is provided with a torque sensor colleting a turning torque signal and a running speed signal and inputting the signals to EPS electric turning controller. The EPS electric turning controller also receives a speed signal and outputs a control signal to a turning motor arranged on the turning shaft. The turning motor drives the direction and the extent of the turning via a drive mechanism connected between the turning motor and a turning output shaft. in the technic proposal provided by the present invention, the engine can stop freely in a hybrid model and the turning system is independent of the work of the engine; therefore the amenity and the security of the whole vehicle is improved.

Description

technical background [0001] Energy shortage and environmental pollution are two major challenges encountered by the development of the automobile industry at present. Relevant data show that 82% of CO and NO in the urban atmosphere x 48% of HC, 58% of HC, and 8% of particulates are all from the exhaust gas emitted by automobiles; according to the prediction of the National Environmental Protection Center, automobile exhaust emissions will account for 64% of air pollution sources in 2010. Since 2000, my country has begun to fully implement new emission regulations. For example, vehicles sold on the market in Beijing at the end of 2005 must meet Euro III emission standards. Over time, national emissions regulations will become more stringent. On the other hand, my country's oil resources are relatively small. Since 1994, my country has been an oil importing country, so energy saving has been put on the agenda; at the same time, after the implementation of fuel tax, improving t...
