Embodiment Construction

[0018] Vehicle Example:

[0019] The vehicle proposed in this embodiment includes such as figure 2 The power steering system shown includes a steering motor and a controller, a storage battery, a power battery, and a DC / DC circuit (ie figure 2 DCDC) and low-voltage power supply lines (generally 12 or 24V lines, the same voltage as the A-level voltage power supply).

[0020] The battery is connected upstream of the low-voltage power supply line, the steering motor and controller are connected in parallel on the low-voltage power supply line, the power battery is connected to the high-voltage side of the DC / DC circuit, the low-voltage side of the DC / DC circuit is connected in parallel to the low-voltage power supply line, and the DC / DC circuit An undervoltage relay (that is, a transistor-type undervoltage relay, also known as a static undervoltage relay) is installed in series on the low-voltage power supply line upstream of the parallel connection point on the low-voltage si...

Abstract

The invention relates to a power steering system and a vehicle, belonging to the technical field of new energy vehicle steering. The system includes steering motor and controller, battery, power battery, DC / DC circuit and low-voltage power supply line. The battery is connected upstream of the low-voltage power supply line. The steering motor and controller are connected in parallel to the low-voltage power supply line. The high-voltage side of the circuit, the low-voltage side of the DC / DC circuit are connected in parallel on the low-voltage power supply line, and an undervoltage relay for detecting short circuit or undervoltage of the battery is installed in series on the low-voltage power supply line upstream of the parallel connection point of the low-voltage side of the DC / DC circuit , the control coil of the undervoltage relay is directly connected in parallel with the storage battery. When the battery is short-circuited or undervoltage, the system disconnects the battery from the DC / DC circuit to prevent the output voltage of the DC / DC from being pulled down, so that the steering motor and the controller are supplied with A-level voltage power by the power battery and the DC / DC circuit , maintain the power steering state and improve driving safety.

Description

technical field [0001] The invention relates to a power steering system and a vehicle, belonging to the technical field of new energy vehicle steering. Background technique [0002] The steering system of modern traditional fuel (gasoline, diesel, CNG, LNG) vehicles includes the following types: mechanical steering system MS, hydraulic power steering system HPS, electrohydraulic power steering system EHPS, electric power steering system EPS. In order to achieve low-speed lightness, high-speed without "fluttering" (that is, the steering force is too light, the road feeling is not strong) to improve the handling stability, while also considering the situation of energy saving, the electro-hydraulic power steering system EHPS and the electric power steering system EPS have been widely used application. [0003] The power steering of the EHPS is provided by the steering motor driving the steering oil pump, and the control circuit of the steering motor and the controller (herein...
