The embodiment of the invention provides a ramp auxiliary system of a hydrogen fuel cell hydrogen energy automobile.
Referring to fig. 1, fig. 1 is a structural diagram of a ramp assisting system of a hydrogen-fuel cell hydrogen-powered vehicle according to an embodiment of the present invention, which specifically includes:
the Vehicle Control Unit (VCU) is connected with a fuel cell system, a power cell system, a driving Motor Controller (MCU) and an anti-lock brake system (ABS) through communication signal lines, the anti-lock brake system can be used for collecting wheel speed signals of each wheel, an inclination angle sensor is arranged in the vehicle control unit and used for collecting gradient information, and the vehicle control unit is further connected with an accelerator pedal and a brake pedal through collecting signal lines. The fuel cell system, the power cell system and the driving Motor Controller (MCU) are connected with the high-voltage distribution box through high-voltage wires, the driving Motor Controller (MCU) is further connected with the driving motor (M) through the high-voltage wires, the power cell system comprises a Battery Management System (BMS), and the fuel cell system comprises a fuel cell management system. The vehicle controller is also connected with an accelerator pedal and a brake pedal through a signal acquisition line and is used for controlling the vehicle to advance and stop.
The torque F required for maintaining the vehicle to stay on the slope is divided into two parts, one part calibrates the corresponding motor torque F1 according to the slope and the vehicle load condition, the other part regulates the torque F2 according to the motor rotating speed in real time PI, and the superposition of the two parts of torques is the target torque which can finally maintain the vehicle to stay on the slope, namely F1+ F2. Because the driving motor is in a locked-rotor state in the slope stopping process, in order to prevent the locked-rotor of the driving motor from burning out, the maximum output time T of the target torque for maintaining the slope stopping process is set according to the performance of the driving motor. The motor rotating speed can be obtained by carrying out speed ratio conversion on the collected wheel speed signals and can also be directly obtained by the driving motor controller, the motor rotating speed obtained by directly collecting the motor rotating speed sensor of the driving motor controller is preferentially used, and when the motor rotating speed sensor of the driving motor controller breaks down, the motor rotating speed obtained by carrying out speed ratio conversion on the collected wheel speed signals is adopted.
The target torque is comprehensively calculated by a Vehicle Control Unit (VCU) according to the current gradient value, the load size and the motor rotating speed and then sent to a driving Motor Controller (MCU) for execution, and meanwhile, the discharging power required by the vehicle is comprehensively calculated according to the residual electric quantity and the residual hydrogen quantity of the power battery and then sent to a fuel battery system and a power battery system. The formula of the comprehensive calculation is as follows: p is a P1+ B P2, where P represents the discharge power required by the vehicle, P1 represents the maximum discharge power of the power battery system, P2 represents the maximum discharge power of the fuel cell system, and a and B are coefficients obtained by common dynamic adjustment according to the remaining amount of power battery system and the remaining amount of hydrogen.
The target torque is increased according to the gradual reduction of the depth of the brake pedal, and when the brake pedal is completely released, the vehicle is parked on the slope in place by adjusting the magnitude of F2 through PI. And in the output process of the hill start target torque F, the vehicle controller responds to the accelerator pedal to output torque. And the whole vehicle controller transmits the target torque in a CAN message mode.
The residual amount of hydrogen is similar to the residual electric quantity of the battery, and the hydrogen is used for predicting the endurance mileage of the vehicle, and reminding a driver of supplementing hydrogen in time when the residual amount is too low.
The invention has the beneficial effects that: the problem that the hydrogen fuel cell automobile slips after starting on a slope is solved, and the hydrogen fuel cell automobile can be realized only by upgrading VCU software on the basis of not increasing the hardware cost of the whole automobile, so that the application cost is low.
