Problems solved by technology

[0002] Dual-source trackless electric heavy-duty trucks have attracted much attention because they can be powered by the grid and do not completely rely on the grid. and the braking system can lose energy supply and cause serious accidents
In addition, due to the large voltage difference between the voltage level of the vehicle power supply and the power grid, large voltage fluctuations will occur when the power supply is switched back and forth during actual operation, and the voltage of the power grid in different time periods and different locations is also different. The impact of each component is relatively large, so the service life of the controller components will be greatly reduced

Abstract

The invention relates to a dual-source trackless electric heavy-duty power-assisted steering and braking system energy supply scheme including a power grid, a vehicle-mounted power supply, a vehicle-mounted emergency backup battery, a voltage fluctuation adjustment module, an all-in-one controller, a power-assisted steering motor and a brake inflating pump motor. The vehicle-mounted power supply and the vehicle-mounted emergency backup battery are connected to the power grid. The voltage fluctuation adjustment module is connected between the all-in-one controller and the power grid and is connected to the vehicle-mounted power supply and the vehicle-mounted emergency backup battery. The multi-in-one controller is internally provided with a power-assisted steering motor control module and a brake inflating pump motor control module. The power-assisted steering motor control module is connected to the power-assisted steering motor, and the power-assisted steering motor is provided with a steering oil pump. The brake inflating pump motor control module is connected to the brake inflating pump motor, and the brake inflating pump motor is provided with a brake inflating pump. According to the dual-source trackless electric heavy-duty power-assisted steering and braking system energy supply scheme, when the power grid and the vehicle-mounted power supply breaks down, the safety work of a power-assisted steering and braking system is ensured, and accidents are avoided; and the current variation range can be reduced, and the service life of the all-in-one controller is prolonged.
