Abstract
Abstract A vehicle control system for controlling its own vehicle to follow another vehicle in pursuit has a radar unit. The radar unit has function for detecting a relative distance from its own vehicle to a front vehicle in front of its own vehicle and a relative speed of the front vehicle with respect to its own vehicle, and outputting information representing the relative distance and the relative speed. A lane change detector detects a lane change which is made by its own vehicle and outputs a lane change signal indicative of the lane change. A processor estimates a future lane or path for its own vehicle from the lane change signal from the lane change detector, unlocks a preceding vehicle which its own vehicle has followed, and determines a new preceding vehicle which its own vehicle is to lock on based on the estimated future lane or path and the information outputted by the radar unit.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
159 words
A vehicle control system for controlling a motor vehicle, the vehicle control system comprising: a radar unit for detecting a relative distance from the motor vehicle to a vehicle in front of the motor vehicle and a relative speed of the vehicle in front of the motor vehicle with respect to the motor vehicle, and outputting information representing the relative distance and the relative speed; a lane change detector for detecting a lane change which is being made by the motor vehicle, and outputting a lane change signal indicative of the lane change being made; and a processor for estimating a future lane or path for the motor vehicle from the lane change signal from the lane change detector, unlocking a preceding vehicle which the motor vehicle has followed, and determining a new preceding vehicle which the motor vehicle is to lock on based on the estimated future lane or path and the information outputted by the radar unit.
Claim 2
Dependent Claim
159 words
A vehicle control system for controlling a motor vehicle, the vehicle control system comprising: a radar unit for detecting a relative distance from the motor vehicle to a vehicle in front of the motor vehicle and a relative speed of the vehicle in front of the motor vehicle with respect to the motor vehicle, and outputting information representing the relative distance and the relative speed; a lane change detector for detecting a lane change which is being made by the motor vehicle, and outputting a lane change signal indicative of the lane change being made; and a processor for estimating a future lane or path for the motor vehicle from the lane change signal from the lane change detector, unlocking a preceding vehicle which the motor vehicle has followed, and determining a new preceding vehicle which the motor vehicle is to lock on based on the estimated future lane or path and the information outputted by the radar unit.
Claim 3
Dependent Claim
54 words
The vehicle control system of claim 1 , wherein the processor further comprises means for determining a vehicle closest to the motor vehicle in the estimated future lane or preceding vehicle which the motor vehicle is to follow based on the estimated future lane or path and the information outputted by the radar unit.
Claim 4
Dependent Claim
46 words
The vehicle control system of claim 1 , wherein the lane change detector comprises a steering angle sensor for detecting a steering angle of the motor vehicle and means for outputting the lane change signal when the detected steering angle is greater than a predetermined threshold.
Claim 5
Dependent Claim
46 words
The vehicle control system of claim 1 , wherein the lane change detector comprises a yaw rate sensor for detecting a yaw rate of the motor vehicle and means for outputting the lane change signal when the detected yaw rate is greater than a predetermined threshold.
Claim 6
Independent Claim
148 words
A method for controlling a motor vehicle, the method comprising the steps of a. detecting a relative distance from the motor vehicle to a vehicle in front of the motor vehicle and a relative speed of the vehicle in front of the motor vehicle with respect to the motor vechicle, and outputting information representing the relative distance and the relative speed, b. detecting a lane change which is being made by the motor vehicle, and outputting a lane change signal indicative of the lane change being made, and c. estimating a future lane or path for the motor vehicle from the lane change signal from detecting the lane change, unlocking a preceding vehicle which the motor vehicle has followed, and determining a new preceding vehicle which the motor vehicle is to lock on based on the estimated future lane or path and the information obtained in Step a.
Claim 7
Independent Claim
148 words
A method for controlling a motor vehicle, the method comprising the steps of a. detecting a relative distance from the motor vehicle to a vehicle in front of the motor vehicle and a relative speed of the vehicle in front of the motor vehicle with respect to the motor vechicle, and outputting information representing the relative distance and the relative speed, b. detecting a lane change which is being made by the motor vehicle, and outputting a lane change signal indicative of the lane change being made, and c. estimating a future lane or path for the motor vehicle from the lane change signal from detecting the lane change, unlocking a preceding vehicle which the motor vehicle has followed, and determining a new preceding vehicle which the motor vehicle is to lock on based on the estimated future lane or path and the information obtained in Step a.
Claim 8
Dependent Claim
41 words
A method as in claim 5 further comprising determining a vehicle closest to the motor vehicle in Step c which the motor vehicle is to follow based on the estimated future lane or path and the information outputted in Step a.
Claim 9
Dependent Claim
32 words
A method as in claim 5 comprising detecting a steering angle of the motor vehicle and outputting the lane change signal when the detected steering angle is greater than a predetermined threshold.
Claim 10
Dependent Claim
32 words
A method as in claim 5 comprising detecting a yaw rate of the motor vehicle and outputting the lane change signal when the detected yaw rate is greater than a predetermined threshold.
