Embodiment Construction

[0026] Such as figure 1 As shown, the cruise control system of the manual gearbox automobile of the present invention is provided with an ECU, and the ECU is provided with an indicator light, and is provided with a cruise control button for inputting control commands, and the cruise control button includes the cruise speed setting plus and minus request signal. "SET / +" and "SET / -" buttons, and "CCSON / OFF" button to control the system switch. In addition, the ECU collects vehicle ignition switch signals, brake signals, clutch signals, accelerator pedal signals, and vehicle speed signals as auxiliary signals. , used to model the policy algorithm for cruise control.

[0027] When the cruise control is enabled, the current vehicle speed and the cruise target vehicle speed are closed-loop controlled, and the vehicle speed control is determined by the engine output torque, which is determined by the intake air volume. Therefore, the cruise speed closed-loop control is realized by ...

Abstract

The invention discloses a cruise control system for a manual transmission automobile and a control method based on the cruise control system. The cruise control system is used for carrying out closed-loop control on a cruise target speed by taking an ignition switch, a cruise request switch and a cruise acceleration / deceleration switch as basic input signals of an intention of a driver, taking a gear signal, a brake switch signal, a clutch switch signal, an accelerator pedal signal and the like as auxiliary input signals and taking an automobile speed signal as a main input signal through controlling the opening of a throttle (the output torque of an engine is controlled by controlling the air inflow), thus realizing the cruise control function of a vehicle. The system and the control method disclosed by the invention are simple in structure, reasonable in control method and safety and reliable to operate.

Description

technical field [0001] The invention relates to the field of automobile electronic control, in particular to the automobile automatic cruise technology. Background technique [0002] Car cruise control can improve the driver's comfort for long-distance driving on the highway. With the improvement of the driver's car comfort, cruise control has become a basic requirement, and it is bound to be a standard configuration on cars in the future. [0003] Car cruise technology has been applied in domestic cars, but there is a lack of automatic cruise control system for the large number of manual transmission cars, so it is necessary to design an automatic cruise control system that can meet the needs of manual transmission cars. Contents of the invention [0004] The technical problem to be solved by the present invention is to realize an automatic cruise system and its control method suitable for manual transmission vehicles. [0005] In order to achieve the above object, the t...
