Abstract
Description
technical field
[0001] The invention relates to the field of electric vehicle manufacturing, and more specifically, relates to a gear switch and a display device of a three-wheeled electric vehicle and a control method thereof. Background technique
[0002] Now some electric vehicles use toggle switches or key switches as gear switches, the gears are fixed, and the gears are changed through mechanical toggles or buttons. The rotary switch is easy to use and has the advantages of multi-gear adjustment. widely used. However, these rotary switches work through the transposition of electrical switches, and are bulky, and an electrical switch or conversion device must be provided for each gear position, which is large and expensive.
[0003] Rotary electronic switches are also used in the prior art, but the rotation is mainly realized by keys and rotation angles. Chinese utility model patent, patent application number 201220706349.3, announced on June 19, 2013. Disclosed is an ...
Examples
Embodiment 1
[0036] Such as figure 1 with figure 2 As shown, a gear switch and display device of a three-wheeled electric vehicle and its control method include a vehicle power supply module 1, a DC-AC boost module 2, a display module drive circuit 3, a main control board 5 and a brake pedal 7 , wherein, the automobile power supply module 1 is connected with the DC-AC step-up module 2 and the main control board 5, and the DC-AC step-up module 2 and the main control board 5 are respectively connected with the display module driving circuit 3, and the DC - The AC step-up module 2 converts the 12V direct current into a 110V, 450Hz alternating current power supply for the display module driving circuit 3 . It also includes a gear position display module 4, a rotary encoder 6 and a parking button 8, wherein the gear position display module 4 is arranged on the car dashboard, and the rotary encoder 6 and the parking button 8 are arranged on the central control. The rotary encoder 6 and the pa...
Embodiment 2
[0047] The implementation of the specific control method is as follows:
[0048] A control method for a gear switch and a display device of a three-wheeled electric vehicle is as follows:
[0049] (a), the vehicle is powered on, and observe whether the gear position display module displays "P"; the gear position is the last stop gear "D", the gear position is automatically switched to N gear, and the gear position display module displays "N";
[0050] (b) Rotate the rotary encoder in reverse, the gear position display module displays "Please step on the brake pedal", at this time step on the brake pedal, and turn the rotary encoder in reverse again;
[0051] (c) Stop rotating the rotary encoder, wait for 1 second, the gear position changes to "R", the gear position display module displays the gear position "R" at this time, and the vehicle is ready to move backward;
[0052] (d) Loosen the brake pedal and start the electric vehicle;
[0053] (e) Depress the brake pedal while...
