Abstract
The invention relates to an electronic accelerator pedal, which includes a spring bushing (1), a gear arm fan (2), a pedal box cover (3), a gear potentiometer (4), a circuit board (5), and a line I Cable harness (6), No. Ⅱ cable harness (7), pedal device (8), fixed plate (9), pedal seat (10), fixed piece (13), bushing (14), shaft (15), Limiting plate (16), small O-ring (17), large O-ring (18), bolt (19), screw (20), screw (21), nut (22), screw (23), electrical connection device (26), passing coil (27) and screw plug (28), the advantages of the present invention are: simple and compact structure, high reliability, good electromagnetic compatibility, linear amplifying transmission system, pedal full-range angle corresponding potentiometer The angle output is the whole process, the signal output is linear, and it has the function of changing the characteristic of the maximum torque output, so that the theoretical stepping angle and the signal output have a linear relationship, and the driving operation accuracy is improved.
Description
technical field [0001] The invention belongs to the technical field of electronic control, and in particular relates to an electronic accelerator pedal. Background technique [0002] As everyone knows, in order to control the oil intake of the motor vehicle oil cylinder, and then control the rotating speed and power of the engine, to finally realize the control of the motor vehicle speed, an accelerator pedal is all provided in the motor vehicle cab. Most of the traditional accelerator pedals are mechanical accelerator pedals, which control the opening of the accelerator through connecting rods or cables. A series of actions are mechanical movements. Since the series of actions of this mechanical accelerator pedal are mechanical movements, Make its transmission precision and sensitivity not high, can't realize fuel saving and accurate control vehicle speed more. [0003] Due to the shortage of mechanical accelerator pedals, many enterprises have developed and produced elect...
