Vehicle idle-speed warning system and idle-speed detection method
First Claim
1. A vehicle warning system disposed on a vehicle, for parking with engine running, the vehicle warning system comprising:
- an input module for enabling a user to enter a preset time;
a timer module for calculating a duration;
a motion information module for providing an engine state information and a displacement information of the vehicle, the motion information module including a single sensor configured to detect a start state of an engine of the vehicle and a speed of the vehicle within a predetermined duration and distance traveled by the vehicle, wherein the motion information module dermines the engine state information and the displacement information in response to the single sensor;
an information processing module for executing control and computation, controlling the timing module to reset the duration to zero when the displacement information indicates a displacement state, actuating the timing module to calculate the duration when the displacement information indicates a non-displacement state, and outputting warning information when the duration exceeds the preset time and the engine state information indicates a running state; and
an output module for reading the warning information and generating a warning message.

Abstract
A vehicle idle-speed warning system and vehicle idle-speed detection method thereof are provided. It is non-invasive, that is, there is no need to change or modify any part of the constructing parts in the engine compartment. The present invention can be adopted stand-alone, or be applied to existing popular apparatuses, such as GPS, driving recorders, smart handheld devices, and vehicle electronic equipments. With the composing elements of a motion information module, an input module, an output module, a timer module and an information processing module, the present invention can accurately determine whether the vehicle under surveillance is in idle state and for how long it is in the idle state, and send an alarm signal automatically. With the implementation of the present invention, drivers can always be alarmed with the vehicle idling situations to prevent possible dangers or coming tickets due to the violation of traffic regulations in certain countries.

15. A detection method, applicable to a vehicle warning system, the detection method comprising the steps of:
-
providing a single sensor for detecting a start state of an engine of the vehicle and a speed of the vehicle within a predetermined duration and distance traveled by the vehicle; determining via a motion information module engine state information and displacement information in response to the single sensor; reading a preset time by an information processing module; reading a state information, wherein the information processing module reads the engine state information and the displacement information from the motion information module; and determining a vehicle idle-speed, wherein the information processing module outputs warning information when the engine state information indicates a start state, the displacement information indicates a non-displacement state, and a parking duration of the vehicle exceeds the preset time.
