Abstract

A control system for a car includes an acceleration sensor, a transforming unit, an analyzing unit, and a control unit. The acceleration sensor detects a movement of an accelerator pedal of the car. The transforming unit transforms the movement of the accelerator pedal into a waveform chart. The analyzing unit analyzes the waveform chart, and determines whether the accelerator pedal is moving rapidly according to the movement. The control unit prevents the car from accelerating when the accelerator pedal moves rapidly.

Claims

1. A control system for a car, comprising:

an acceleration sensor for detecting movement of an accelerator pedal of the car;

an analyzing unit for analyzing the movement, and determining whether the accelerator pedal moves rapidly according to the movement; and

a control unit for preventing the car from accelerating when the accelerator pedal moves rapidly.

2. The control system as claimed in claim 1, further comprising a transforming unit for transforming the movement of the accelerator pedal into a waveform chart, and the analyzing unit analyzing the waveform chart to determine whether the accelerator pedal is moving rapidly.

3. The control system as claimed in claim 1, further comprising:

a mode switch unit for setting a first mode or a second mode for the control system, wherein the acceleration sensor, the analyzing unit, and the control unit is initiated when the control system is set to the first mode;

a status determining unit for determining whether the car speed is above a pre-determined threshold, or the car is in reverse gear; and

an enabling unit for initiating the acceleration sensor, the analyzing unit, and the control unit when the car speed is above the pre-determined threshold, or the car is in reverse gear.

4. The control system as claimed in claim 1, wherein the acceleration sensor is arranged on the accelerator pedal.

5. A control method for controlling a car, comprising:

detecting movement of an accelerator pedal of the car;

determine whether the accelerator pedal is moving rapidly according to the movement; and

controlling the car not to accelerate when the accelerator pedal moves rapidly.

6. The control method as claimed in claim 5, further comprising:

transforming the movement into a waveform chart which is used to determine whether the accelerator pedal is moving rapidly according to the movement of the accelerator pedal.

7. A control method for controlling a car, comprising:

determining whether a speed of the car is above a pre-determined threshold, or the car is in reverse gear when the control system is set to the auto mode;

detecting the movement when the speed is above a pre-determined threshold, or the car is in reverse gear;

transforming the movement into a waveform chart which is used to determine whether the accelerator pedal moves rapidly according to the movement of the accelerator pedal; and

controlling the car not to accelerate when the accelerator pedal moves rapidly.
