Embodiment Construction

[0010] The present invention will be described in further detail below in conjunction with accompanying drawing embodiment:

[0011] figure 1 The vehicle dual-accelerator control system shown includes a pedal-type electronic accelerator 2 connected to the engine ECU unit 4, an accelerator switch 1, and a knob-type manual electronic accelerator 3. The engine ECU unit 4 communicates with the micro-processing module 5 through the CAN bus. connected; during work, the engine ECU unit 4 first detects the switch signal input by the throttle switch 1; when the throttle switch 1 is in an off state, the throttle switch 1 outputs a preset disconnection switch signal to the engine ECU unit 4, and the engine After the ECU unit 4 detects that the signal is a disconnect switch signal, it only receives the electric signal of the pedal electronic throttle 2 as the throttle control condition, and the knob type manual electronic throttle is invalid. At this time, the engine ECU unit 4 receives a...

Abstract

The invention discloses a vehicle double-throttle control system, and belongs to the technical field of automobile manufacturing. The system comprises a pedal type electronic throttle, a throttle switch and a knob type manual control electronic throttle which are connected with an engine ECU (Electronic Control Unit), wherein the engine ECU detects a switch signal input by the throttle switch during work; when the switch signal is a preset cut-off signal, the engine ECU only receives the signal of the pedal type electronic throttle, the knob type manual control electronic throttle becomes invalid, and the rotation speed of an engine is controlled by adjusting the opening of the pedal type electronic throttle at the time; when the switch signal is a preset turn-on signal, the engine ECU only receives the signal of the knob type manual control electronic throttle, the pedal type electronic throttle becomes invalid, and the rotation speed of the engine is controlled by adjusting the opening of the knob type manual control electronic throttle at the time. According to the system, the problem that fatal crash accidents are easily caused due to overstrain of a driver because of a single pedal type throttle in long-distance driving can be solved.

Description

technical field [0001] The invention relates to the technical field of automobile manufacturing, in particular to a control system of dual accelerators for a vehicle. Background technique [0002] In automobile manufacturing, traditional automobile accelerators mostly use pedal-type electronic accelerators. The control of pedal-type electronic accelerators is to first output the electric signal of the speed of the car to the engine ECU unit of the car through the depth of the pedal, and the engine ECU unit of the car. The electric signal is analyzed, and the driving signal of the external motor is output, and then the external motor pulls the throttle swing rod to make the engine work at the corresponding throttle opening, so as to control the engine speed. With the advancement of automobile technology, people have developed a knob-type manual electronic throttle. The control of the knob-type manual electronic throttle is to first output the electric signal of the speed of t...
