Example Embodiment
[0041] Embodiment 1: Implement the specific method of the present invention in the electric vehicle controller:
[0042] Electric vehicle controller is a typical embedded system product. It contains a microcontroller and its associated circuits. Its typical input devices are: accelerator (for example: turning handle, pedal, etc.), brake (brake handle, pedal, etc.), etc.; typical output devices are: indicator light, horn (buzzer, etc.). The configuration of the electric vehicle controller can be completed by using these existing conventional input and output devices, and the method is as follows:
[0043] In conventional designs, users are usually prohibited from performing some dangerous and unreasonable operations. For example: set the accelerator to the acceleration state, and then turn on the power of the controller (this operation is called "high pedal"); or set the accelerator to the acceleration state, and use the brake at the same time, etc. If the user performs the ...
Example Embodiment
[0056] Example 2: Using an accelerator to form quantitative intentions through qualitative operations:
[0057] 1. For a one-way accelerator, initialize the controller internal variable (parameters that need to be configured) A to 0. definition:
[0058] 1. Every time the accelerator changes from the non-accelerating state to the accelerating state, then A increases by 1;
[0059] 2. If there is no input signal for 2 seconds, it means that the user input is completed;
[0060] 3. After the user completes the input, the value of variable A is the data input by the user this time. For example: use 'back' to indicate that the user-operated accelerator is in a non-accelerating state, which does not exceed 2 seconds; use 'plus' to indicate that the user-operated accelerator is in an accelerating state; use 'stop' to indicate that the user-operated accelerator is in a non-accelerating state for more than 2 seconds. If the user operates the accelerator in the following sequence: b...
