Abstract

The invention discloses a vehicle speed limit control system. The vehicle speed limit control system comprises a vehicle speed monitoring unit and an engine control unit. The engine control unit is connected with the vehicle speed monitoring unit, and the vehicle speed monitoring unit monitors the running speed of the vehicle and the current speed limit range in real time. The engine control unitreceives the running speed of the vehicle and the current speed limit range which are sent by the vehicle speed monitoring unit and limits the running speed of the vehicle within the current speed limit range by controlling the throttle output. According to the vehicle speed limit control system, the running speed and the current speed limit range of the vehicle are automatically obtained in realtime by monitoring the electric signal change of a photovoltaic panel and the duration of the electric signal change, and manual setting of the speed limit value is not required. The invention furtherdiscloses a control method of the vehicle speed limit control system.

Description

technical field [0001] The invention belongs to the technical field of vehicle control, in particular to a vehicle speed limit control system and control method. Background technique [0002] Photovoltaic roads use photovoltaic panels to convert solar energy into electrical energy to provide power for themselves. The electrical signal obtained by this power supply method is affected by the intensity of light. Small. For a photovoltaic panel in a fixed area, when there is no vehicle passing by, the light intensity on it is stable, and the electrical signal it acquires is also stable. When a vehicle passes by, the light intensity on it gradually weakens to The minimum value is then gradually increased to a stable value. Similarly, the electrical signal it acquires also undergoes a process of gradually weakening to a minimum value and then gradually increasing to a stable value. Therefore, the change of the electrical signal acquired by the photovoltaic panel can be obtained ...
