Claims
- 1. A vehicle speed control apparatus comprising:detecting apparatus configured to detect a headway distance and a relative speed of a host vehicle in relation to a preceding vehicle; detecting apparatus configured to detect an own speed of said host vehicle; computer apparatus configured to compute a speed of said preceding vehicle based on said own speed and said relative speed of said host vehicle; and controlling apparatus configured to the speed of said preceding vehicle passing a given point and which controls at least one of a throttle valve device, a transmission device and a braking device so that said own speed of said host vehicle passing said point does not exceed the stored speed of said preceding vehicle.
- 2. A vehicle speed control apparatus according to claim 1, wherein said controlling apparatus is operatively configured to control said own speed of said host vehicle if said preceding vehicle directionally deviates by a predetermined angle from a frontal direction of said host vehicle.
- 3. A vehicle speed control apparatus according to claim 1, wherein said controlling apparatus is operatively configured to control said own speed of said host vehicle if said preceding vehicle is found turning in direction.
- 4. A vehicle speed control apparatus according to claim 1, wherein said controlling apparatus is configured to control said own speed of said host vehicle so that said headway distance to said preceding vehicle exceeds a predetermined value.
- 5. A vehicle speed control apparatus comprising:detecting apparatus configured to detect a headway distance and a relative speed of a host vehicle in relation to a preceding vehicle; detecting apparatus configured to detect an own speed and a yaw rate of said host vehicle; computer apparatus configured to compute a speed of said preceding vehicle based on said own speed and said relative speed of said host vehicle; and controlling apparatus configured such that, if said yaw rate of said host vehicle is in excess of a predetermined value, the speed of said preceding vehicle passing a given point is stored, said controlling apparatus further being configured to control at least one of a throttle valve device, a transmission device and a braking device so that said own speed of said host vehicle passing said point does not exceed both a speed determined by said yaw rate of said host device and the stored speed of said preceding vehicle.
- 6. A vehicle speed control apparatus comprising:detecting apparatus configured to detect a headway distance and a relative speed of a host vehicle in relation to a preceding vehicle; detecting apparatus configured to detect an own speed and a yaw rate of said host vehicle; computing apparatus configured to compute a speed of said preceding vehicle based on said own speed and said relative speed of said host vehicle; and controlling apparatus configured such that, if host vehicle loses sight of said preceding vehicle and if said yaw rate of said host vehicle is in excess of a predetermined value, at least one of a throttle valve device, a transmission device and a braking device is controlled so that said own speed of said host vehicle does not exceed both the speed of said preceding vehicle in effect when said host vehicle lost sight of said preceding vehicle and a speed determined by said yaw rate of said host device.
