Detailed Description
The invention is described in detail below with reference to the figures and specific embodiments.
Example (b):
the invention provides a driving control device for a new energy bus. The accelerator of the vehicle can be directly controlled by manually shifting the shifting piece.
The contents related to this embodiment include the following: the software part needs to change the control strategy of the whole vehicle, the hardware part needs to develop a new poking sheet type switch, and part of the circuit principle and the corresponding wiring harness need to be modified.
The invention has the greatest characteristics that the power control of the foot pedal is transferred to the hand shifting operation, only the finger needs to shift lightly, and the power control is easy and accurate; an accelerator pedal is cancelled, only a brake pedal is reserved, and when an emergency occurs, the driver can directly step on the accelerator pedal without thinking; the accelerator is controlled by dialing the switch with fingers, so that the physical workload of a driver is greatly reduced, the fatigue degree of the driver is reduced, and the driving safety is improved.
The working principle of the invention is as follows:
in the driving process, the plectrum switch is shifted, and after the VCU receives a pulse signal of the plectrum switch, the current driving state of the vehicle is judged, and instructions such as acceleration, uniform speed, deceleration and the like of the vehicle are executed. When the right side shifting piece switch is pulled, the speed is increased, when the left side switch is pulled, the speed is reduced, and the shifting piece switch is an automatic return type switch.
According to the novel driving mode, a driver realizes accelerator control through a fixed shifting piece switch. It should be noted that if the vehicle needs to be accelerated during steering, the right hand needs to be vacated to dial the right side shifting piece. The following will describe in detail the specific operation and control flow, the overall vehicle control strategy, the circuit principle and the composition structure, etc.

The left shifting piece is clicked in any acceleration cycle, so that the vehicle can keep the current speed to run at a constant speed; no plectrum is operated in the acceleration cycle, and the vehicle keeps running at a constant speed after being accelerated to the highest speed of the current acceleration cycle.
3. When the vehicle is at a constant speed, the right side shifting piece is clicked, and as long as the vehicle is not at the highest speed, the vehicle enters an acceleration cycle; and when the left shifting piece is clicked at a constant speed, the vehicle interrupts power output until the vehicle stops.
4. When the power is not output, the right shifting piece is clicked, and the vehicle enters an acceleration cycle.
5. The power output can be interrupted unconditionally when the brake pedal is stepped down; any paddle action is ineffective when the brake pedal is depressed.
