Abstract

Abstract The present invention compensates for a variability in steering angle of a wheel when a vehicle has been stopped, thereby performing an accurate automatic steering. To guide a vehicle stopped at a start position via a reversing position to a target position, the vehicle is automatically steered based on data for a steering angle of a wheel relative to a previously stored traveling distance of the vehicle. The steering angle at the time when the vehicle is stopped at the start position (1) is varied every time and is not necessarily equal to an initial standard steering angle intended to start an automatic steering control. Therefore, at the start position, the automatic steering control of the vehicle is started after equalizing the steering angle of the wheel to the initial standard steering angle, so that the vehicle can be correctly guided to the target position.

Claims Analysis

Total Claims: 12
Claim 1
Independent Claim 132 words
An automatic steering system for a vehicle, comprising: a movement locus setting means for one of storing and calculating a locus of movement of a vehicle to a target position; an actuator adapted to steer wheels of the vehicle; and a control means for controlling driving of said actuator based on the locus of movement set by said movement locus setting means, while the vehicle moves from a start position to a target position, wherein said control means permits said actuator to be controlled based on the locus of movement after equalizing a steering angle of the wheels to an initial standard steering angle by said actuator, when the vehicle has been shifted from a stopped state to a moving state at a point in time to perform movement of the vehicle.
Claim 2
Dependent Claim 132 words
An automatic steering system for a vehicle, comprising: a movement locus setting means for one of storing and calculating a locus of movement of a vehicle to a target position; an actuator adapted to steer wheels of the vehicle; and a control means for controlling driving of said actuator based on the locus of movement set by said movement locus setting means, while the vehicle moves from a start position to a target position, wherein said control means permits said actuator to be controlled based on the locus of movement after equalizing a steering angle of the wheels to an initial standard steering angle by said actuator, when the vehicle has been shifted from a stopped state to a moving state at a point in time to perform movement of the vehicle.
Claim 3
Dependent Claim 168 words
An automatic steering system for a vehicle, comprising: a movement locus setting means for one of storing and calculating loci of movement of a vehicle to a plurality of target positions; an actuator adapted to steer wheels of the vehicle; and a control means for controlling driving of said actuator based on the locus of movement set by said movement locus setting means, while the vehicle moves from a start position to a target position; a selecting means for selecting a locus of movement to any of the plurality of target positions; and a start indicating means for starting control of said actuator based on the selected locus of movement, wherein said control means permits said actuator to be controlled based on the locus of movement after equalizing a steering angle of the wheels to an initial standard steering angle by said actuator, when the vehicle has been shifted from a stopped state to a moving state at a point in time to perform movement of the vehicle.
Claim 4
Dependent Claim 168 words
An automatic steering system for a vehicle, comprising: a movement locus setting means for one of storing and calculating loci of movement of a vehicle to a plurality of target positions; an actuator adapted to steer wheels of the vehicle; and a control means for controlling driving of said actuator based on the locus of movement set by said movement locus setting means, while the vehicle moves from a start position to a target position; a selecting means for selecting a locus of movement to any of the plurality of target positions; and a start indicating means for starting control of said actuator based on the selected locus of movement, wherein said control means permits said actuator to be controlled based on the locus of movement after equalizing a steering angle of the wheels to an initial standard steering angle by said actuator, when the vehicle has been shifted from a stopped state to a moving state at a point in time to perform movement of the vehicle.
Claim 5
Dependent Claim 40 words
An automatic steering system for a vehicle according to claim 2, wherein when the locus of movement is selected by said selecting means, the steering angle of the wheels is equalized to the initial standard steering angle by said actuator.
Claim 6
Dependent Claim 35 words
An automatic steering system for a vehicle according to claim 2, wherein operation of said start indicating means is prohibited until the steering angle of the wheels is equalized to the initial standard steering angle.
Claim 7
Dependent Claim 35 words
An automatic steering system for a vehicle according to claim 3, wherein operation of said start indicating means is prohibited until the steering angle of the wheels is equalized to the initial standard steering angle.
Claim 8
Dependent Claim 38 words
An automatic steering system for a vehicle according to claim 1, including a brake means operated by a driver, wherein driving of said actuator based on the locus of movement is permitted when said brake means is operated.
Claim 9
Dependent Claim 38 words
An automatic steering system for a vehicle according to claim 2, including a brake means operated by a driver, wherein driving of said actuator based on the locus of movement is permitted when said brake means is operated.
Claim 10
Dependent Claim 38 words
An automatic steering system for a vehicle according to claim 3, including a brake means operated by a driver, wherein driving of said actuator based on the locus of movement is permitted when said brake means is operated.
Claim 11
Dependent Claim 38 words
An automatic steering system for a vehicle according to claim 4, including a brake means operated by a driver, wherein driving of said actuator based on the locus of movement is permitted when said brake means is operated.
Claim 12
Dependent Claim 38 words
An automatic steering system for a vehicle according to claim 5, including a brake means operated by a driver, wherein driving of said actuator based on the locus of movement is permitted when said brake means is operated.
