Embodiment Construction

[0027] Specific embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings. It should be understood that the specific embodiments described here are only used to illustrate and explain the present invention, and are not intended to limit the present invention.

[0028] figure 1 It is a schematic diagram of a contact type accelerator pedal position sensor used in the prior art. like figure 1 As shown, the contact type accelerator pedal position sensor 10 includes a sliding rheostat, the coil of the sliding rheostat is arc-shaped, and the brush 103 is connected to the accelerator pedal 20 through a rotating shaft 1031 . When the accelerator pedal 20 is depressed, its depth (the percentage of the angle at which the accelerator pedal is depressed to the maximum angle at which it can be depressed) changes, driving the electric brush 103 to rotate. The two ends 101 and 102 of the coil of the sliding rheostat are loaded wit...

Abstract

The invention discloses a contact-type throttle pedal position sensor, a throttle control system and a vehicle. The contact-type throttle pedal position sensor comprises a slide rheostat which comprises a coil and a brush, wherein the coil comprises a first end and a second end; under the condition of loading an input voltage between the first end and the second end, the output voltage between the first end and the brush is used for expressing the depth of a throttle pedal, wherein the coil is configured such that the unit length resistance of the coil gradually decreases from the first end to the second end. Accordingly, when starting or driving at a low speed, the vehicle can rapidly speed up by lightly stepping on the throttle pedal, thereby meeting power demands more rapidly.

Description

technical field [0001] The invention relates to the field of automobile electronic control, in particular to a contact type accelerator pedal position sensor, an accelerator control system and a vehicle. Background technique [0002] At present, the electronic accelerator control system of a vehicle is mainly composed of an accelerator pedal, an accelerator pedal position sensor, an electronic control unit (ECU), a servo motor, and a throttle actuator. The accelerator pedal position sensor can transmit the depth information of the accelerator pedal to the ECU, and the ECU outputs a control signal according to the depth information, which is transmitted to the motor, and the motor drives the throttle actuator to realize the electronic control of the throttle function. [0003] Among them, the contact type (potentiometer type) accelerator pedal position sensor works on the principle of a voltage divider circuit. Wherein, the sensor includes a sliding rheostat, and the voltage...
