A control method for a vehicle auxiliary system

Abstract

The invention discloses a control method of a vehicle auxiliary system, which includes controlling the auxiliary drive source to start; acquiring the state of the electrical equipment and judging whether the electrical equipment is normal according to the state of the electrical equipment; if not, controlling the output speed of the auxiliary drive source to be 0 rpm ; If yes, acquiring the execution device status and controlling the auxiliary driving source to drive the execution device at a target output speed according to the execution device status. Through the above method, no complex electrical structure is required, the structure is simplified, and failure points are reduced, and reliability is improved. Realize system redundancy, adopt independent dual-source drive mode, and use braking energy to drive loads at the same time, energy-saving and high-efficiency, generalized and modular hardware configuration, strong environmental adaptability, and more convenient installation and layout. Increased system diagnosis, fault identification and other strategies to improve driving safety.

Description

technical field [0001] The invention relates to the field of vehicles, in particular to a control method of a vehicle auxiliary system. Background technique [0002] In order to ensure the safety and stability of the vehicle, the vehicle generally includes a power system and an auxiliary system, etc. The power system provides power for the vehicle, and the auxiliary system realizes functions such as steering, braking and cooling. The oil pump controls the steering gear, the electric air compressor controls the brakes, and the electric water pump controls the cooling water circulation. [0003] However, this method has complex electrical structure, many failure points, high cost, and poor reliability, versatility, and environmental adaptability. When the electrical system is abnormal, it will cause instantaneous steering failure and return to normal, which will cause driving safety. Vehicle lock affects operation. The electric steering pump rotates constantly during driving...

Problems solved by technology

Each subsystem adopts independent heat dissipation or natural cooling. For example, air compressors mostly adopt air cooling, which requires high ventilation and heat dissipation. In addition, it is difficult for the oil temperature of the compressor lubrication system and the temperature of the motor to reach the ideal state at the same time; for example, the hydraulic system is due to Low load, low heat dissipation under typical working conditions, generally no independent temperature control device is added, but in low temperature environment, it is easy to cause noise due to viscosity of hydraulic oil, etc.
