Abstract
Abstract A cruise control system for a motor vehicle (10) includes a forward looking distance sensor (20) adapted to sense vehicles (11, 12, 13) moving in the same path as the equipped vehicle (10) or in paths adjacent to the equipped vehicle (10), the system tracking vehicles (11, 12, 13) in front of or in paths adjacent to the equipped vehicle (10) and controlling braking or acceleration of the equipped vehicle (10) in response to vehicles (11, 12, 13) travelling in front of or on converging paths with the equipped vehicle (10), in order to maintain a safe distance between the equipped vehicle (10) and vehicles (11, 12, 13) in or entering its path.

Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
185 words
A cruise control system for a motor vehicle (10) comprising a forward looking distance sensor means (20), the distance sensor means (20) being capable of sensing vehicles (11) moving in the same path as the equipped vehicle (10) and controlling the speed of the equipped vehicle (10) in order to maintain a safe distance with the vehicles (11) in front, characterised in that the sensor means (20) also senses vehicles (12, 13) moving in paths adjacent to the path of the equipped vehicle (10); means (22 - 30) being provided to process signals from the sensor means (20) to provide information of the range, relative velocity and direction of movement of vehicles (11, 12, 13) travelling in front of or in paths adjacent to the equipped vehicle (10); and means (40) being provided to control braking and acceleration of the equipped vehicle (10) in response to vehicles (11, 12, 13) travelling in front of or on converging paths with the equipped vehicle (10), in order to maintain a safe distance between the equipped vehicle (10) and vehicles (11, 12, 13) in or entering its path.
Claim 2
Dependent Claim
21 words
A cruise control system according to Claim 1 characterised in that the forward looking sensor means (20) is a radar sensor.
Claim 3
Dependent Claim
29 words
A cruise control system according to Claim 1 or 2 characterised in that the sensor means (20) has a field of view of the order of 15° or greater.
Claim 4
Dependent Claim
33 words
A cruise control system according to any one of the preceding claims characterised in that the forward looking sensor means (20) comprises a single sensor which is scanned mechanically from side to side.
Claim 5
Dependent Claim
42 words
A cruise control system according to any one of the preceding claims characterised in that the sensor means (20) comprises an array of sensors angled with respect to one another to cover the required field of view, the sensors being scanned electronically.
Claim 6
Dependent Claim
122 words
A cruise control system according to any one of the preceding claims characterised in that means (28, 30) is included for monitoring successive signals from each object detected by the sensor means (20) and from said signals selecting the possible targets (11, 12, 13) corresponding to objects moving in the same direction as the equipped vehicle (10) in the path of the equipped vehicle (10) or in paths adjacent to the equipped vehicle (10); means (26) for tracking each possible target and for selecting a most appropriate target and means (40) for controlling acceleration or deceleration of the vehicle (10) in response to the relative position and speed of the most appropriate target (11, 12, 13) relative to the equipped vehicle (10).
Claim 7
Dependent Claim
37 words
A cruise control system according to any one of the preceding claims characterised in that acceleration or deceleration of the vehicle (10) is controlled by means of the throttle system and/or braking system of the vehicle (10).
Claim 8
Dependent Claim
29 words
A cruise control system according to Claim 7 characterised in that servo means (46, 48) are provided to control the throttle system and/or braking system of the vehicle (10).
Claim 9
Dependent Claim
36 words
A cruise control system according to any one of Claims 1 to 7 characterised in that the throttle system and/or braking system of the vehicle (10) is controlled through the engine or braking management control system.
Claim 10
Dependent Claim
