Embodiment 1

[0053]Embodiment 1: as figure 1 , 2 As shown, a speed limiting system for a coach car includes a vehicle-mounted drive signal source 3, an ECU, and a vehicle-mounted actuator 4. The vehicle-mounted drive signal source 3 sends a drive signal to the ECU, and the ECU sends a control signal to the vehicle-mounted actuator 4. On the signal transmission path composed of the signal source 3, the ECU, and the vehicle actuator 4, a speed-limiting control circuit 100 is set;

[0054] The speed limit control circuit 100 is provided with a signal source processing circuit 1 and a switching circuit 2, and the switching circuit 2 is provided with two input terminal groups and one output terminal group;

[0055] Wherein the first input terminal group is connected with the output terminal of the signal source processing circuit 1, and the input terminal group of the signal source processing circuit 1 is connected with the monitoring signal source circuit 5;

[0056] The second input termina...

Embodiment 2

[0078] The structure principle of present embodiment 2 is consistent with embodiment 1, and its difference is:

[0079] like Figure 9 As shown: the second input terminal group of the switching circuit 2 is connected to the ECU, and the ECU is connected to the vehicle driving signal source 3 , and the output terminal group of the switching circuit 2 is connected to the vehicle actuator 4 .

[0080] However, it should be pointed out that when the vehicle-mounted actuator 4 needs to input digital signals, an analog-to-digital converter needs to be installed at the first input terminal group of the switching circuit 2, that is, the output terminal of the amplifying circuit, to simulate the output of the ECU. digital signal.

Abstract

The invention discloses an instructional vehicle speed limiting system. The instructional vehicle speed limiting system comprises a vehicle-mounted driving information source, an electronic control unit (ECU) and a vehicle-mounted actuator. A vehicle-mounted driving information source output end set is connected with a speed limiting control circuit. The vehicle speed control end of the speed limiting control circuit is connected with the ECU. The output end of the ECU is connected with the vehicle-mounted actuator. The monitoring end of the speed limiting control circuit is further connected with a monitoring information source circuit. The speed limiting control circuit is provided with an information source processing circuit and a switching circuit. The switching circuit is provided with two ways of input end sets and one way of output end set. The first way of input end set of the switching circuit is connected with the output end of the information source processing circuit. An input end set of the information source processing circuit is connected with the monitoring information source circuit. The second way of input end set of the switching circuit is connected with the vehicle-mounted driving information source. The output end set of the switching circuit is connected with the ECU. The instructional vehicle speed limiting system has the remarkable effects that forcing speed limitation can be achieved when a student drives, and reliable control over the vehicle speed is achieved in a safe speed limiting range.

Description

technical field [0001] The invention relates to an automobile circuit technology, specifically a speed limiting system for a coach car. Background technique [0002] The vehicle speed control system of existing vehicles is generally determined by the gear position of the transmission and the opening of the throttle valve. The ECU of the car adjusts the opening of the throttle valve of the engine by reading the voltage amplitude of the throttle sensor. But in the trainer car, when the trainee drives the trainer car alone, due to unskilled operation, it is easy to use the accelerator as a brake, and because there is no speed control device, the speed of the car will suddenly increase, causing accidents. [0003] In order to avoid tragedies caused by misoperation by students, it is necessary to design a speed control circuit specifically for the coach car, which can enforce a speed limit when the students are driving. The speed control circuit controls the speed signal input t...
