Abstract
An automatic cruise control method for vehicles is initiated by firstly selecting an automatic cruise mode. Then a current vehicle speed is detected and the current vehicle speed is compared with a target speed. Next, a new target speed is obtained according to the comparison and an amount of fuel to be injected is determined according to the new target speed .
Claims10
An automatic cruise control method for a vehicle having an engine for providing power to drive the vehicle, the method comprising the steps of:
- selecting a target speed for an automatic cruise mode;
- detecting a current vehicle speed;
- comparing the current vehicle speed with the target speed;
- determining a new target speed wherein when the current speed is lower than the target speed the new target speed is set equal to the sum of the target speed and the difference between the target speed and the current speed, and wherein when the current speed is higher than the target speed the new target speed is set equal to the current speed;
- and
- controlling an amount of fuel to be injected to the vehicle engine for attaining the new target speed.
An automatic cruise control method for a vehicle having an engine for providing power to drive the vehicle, the method comprising the steps of:
- selecting a target speed for an automatic cruise mode;
- detecting a current vehicle speed;
- comparing the target speed to the current speed;
- setting a new target speed greater than the target speed when the current speed is lower than the target speed,
- controlling an amount of fuel to be injected to the vehicle engine for attaining the new target speed;
- stopping the fuel injection to the engine, and
- setting a new target speed lower than the target speed when the current speed is higher than the target speed;
- and
- providing fuel injection to the engine for attaining the new target speed when the new target speed is greater than the current speed.
An automatic cruise control method for a vehicle having a driving means tor driving the vehicle, the method comprising the steps of:
- selecting a target speed for an automatic cruise mode;
- detecting a current vehicle speed;
- comparing the current vehicle speed with the target speed;
- determining a new target speed wherein when the current speed is lower than the target speed the new target speed is set equal to the sum of the target speed and the difference between the target speed and the current speed, and wherein when the current speed is higher than the target speed than the new target speed is set equal to the current speed;
- and
- controlling the driving means for attaining the new target speed.
