Abstract
A vehicle cruise control apparatus is provided for controlling a vehicle to run at a set speed desired by a driver. The apparatus stores a state in which the driver inputs a set speed (for example, the number of times the driver inputs the set speeds and a period at which the driver inputs the set speeds), and calculates a target acceleration/deceleration from the input state and a vehicle speed deviation (calculated by subtracting the actual vehicle speed from the set speed).
Claims6
A vehicle cruise control apparatus for controlling a vehicle to run at a set speed desired by a driver, said apparatus comprising:
- actual vehicle speed detecting means for detecting an actual speed of the vehicle;
- setting means for allowing the driver to operate a desired set speed;
- set speed storage means for storing the set speed;
- driver set speed input state detecting means for detecting a state in which the driver inputs the set speed using said setting means;
- target acceleration/deceleration calculating means for calculating a target acceleration/deceleration based on the driver set speed input state and a vehicle speed deviation when the target acceleration/deceleration is calculated to match the actual vehicle speed with the set speed;
- and
- means for controlling a throttle actuator based on the target acceleration/deceleration to increase or decrease the engine power.
A vehicle cruise control method comprising the steps of:
- reading a vehicle speed set by a passenger;
- and
- controlling an actual vehicle speed based on an input state represented by a frequency at which the passenger changes the set speed, and a currently set speed.
