Embodiment Construction
[0025] The specific implementation manners of the present invention will be further described in detail below in conjunction with the accompanying drawings.
[0026] Such as figure 1 In the drive control system of the electric bus shown, the electric bus uses a capacitor battery pack connected to the power receiving device to form an electric bus power receiving and energy storage circuit. The capacitor battery pack passes through the high-voltage electric control box, the main control circuit electronic , The drive power control device is connected with the drive motor to form the main electric drive circuit. The drive control system includes a low-voltage module control system; BMS battery management system; low-voltage control box; DC-DC power converter; display instrument; IGBT chopper speed regulation box; the vehicle controller; the 24V battery that supplies power to the low-voltage module and the BMS battery management system through the low-voltage control box; the veh...

The invention discloses an electric motor coach drive control system and method. The drive control system comprises a low-voltage module control system, a BMS battery management system, a low-voltage control box, a DC-DC power converter, a display instrument, an IGBT chopped wave speed regulating box, a vehicle control unit, a storage battery, a vehicle power switch, a drive motor speed sensor, an air compressor temperature sensor and a vehicle door drive air cylinder electromagnetic valve switch and power sources of all the components. The control method comprises the steps that the position of a pantograph is monitored after a powered device is raised; when the pantograph of the operated powered device is separated from a power grid, the low-voltage module control system detects whether a pantograph travel switch is in a turned-off state or not, and meanwhile the BMS battery management system detects whether charging current still exits on a charging loop or not; when the pantograph travel switch is in a turned-off state and meanwhile the charging loop has no charging current, the pantograph can be separated from the power grid; an air compressor frequency converter power source is controlled; a vehicle door opening safety prompt is sent; parameters and charging of all the components and capacitor battery packs are controlled.
Description
technical field [0001] The invention relates to the technical field of electric vehicles, in particular to a driving control system and a control method for an electric passenger vehicle. Background technique [0002] At present, in the field of public transportation and automobile transportation in modern cities, vehicles powered by traditional petroleum still occupy a very large proportion, which not only consumes a large amount of petroleum resources, but also causes environmental pollution, increases the concentration of urban PM2.5, and excessive fuel consumption Car operation affects people's health, so new energy vehicles with the theme of energy saving and environmental protection have been developed worldwide. [0003] Chinese patent application number 200710014576.3, publication number CN101037092A disclosed a capacitor traction electric car on September 19, 2007. It specifically discloses that a capacitor traction electric car adopts a super-large-capacity tracti...
