Abstract

Abstract An automatic steering system for appropriately maintaining an operational amount of a brake pedal in carrying out automatic parking control, while allowing a vehicle to creep. Data for a steering angle of a wheel relative to a distance of movement of a vehicle is previously stored in a memory section in correspondence to four parking modes. If a desired parking mode is selected by a mode selecting switch and a driver permits the vehicle to creep, while depressing a brake pedal, a control section controls the operation of a steering actuator to carry out automatic parking. A reference operational amount for the brake pedal, is previously set so as to provide an appropriate vehicle creep speed, and if a deviation between an actual operational amount of the brake pedal detected by a brake operational amount detecting means and the reference operational amount exceeds a predetermined value, a warning is emitted by a warning means to the driver, in order to urge the driver to regulate the actual operational amount of the brake pedal.

Claims Analysis

Total Claims: 6
Claim 1
Independent Claim 135 words
An automatic steering system for a vehicle, comprising: a movement locus setting means for storing a locus of movement of a vehicle to a target position, an actuator adapted to steer at least one wheel of the vehicle wheel based upon the locus of movement set by said movement locus setting means, a brake input means operated by a driver to brake the vehicle, an actuator driving control means coupled to said actuator for operating said actuator when said brake input means is operated, a brake operational amount detecting means for detecting an actual operational amount of said brake input means, and a deviation calculating means, coupled to said brake operational amount detecting means, for calculating a deviation between the detected actual operational amount and a preset reference operational amount of said brake input means.
Claim 2
Dependent Claim 135 words
An automatic steering system for a vehicle, comprising: a movement locus setting means for storing a locus of movement of a vehicle to a target position, an actuator adapted to steer at least one wheel of the vehicle wheel based upon the locus of movement set by said movement locus setting means, a brake input means operated by a driver to brake the vehicle, an actuator driving control means coupled to said actuator for operating said actuator when said brake input means is operated, a brake operational amount detecting means for detecting an actual operational amount of said brake input means, and a deviation calculating means, coupled to said brake operational amount detecting means, for calculating a deviation between the detected actual operational amount and a preset reference operational amount of said brake input means.
Claim 3
Dependent Claim 132 words
An automatic steering system for a vehicle, comprising: a movement locus setting means for calculating a locus of movement of a vehicle to a target position, an actuator adapted to steer a wheel of the vehicle based upon the locus of movement set by said movement locus setting means, a brake input means operated by a driver to brake the vehicle, an actuator driving control means coupled to said actuator for operating said actuator when said brake input means is operated, a brake operational amount detecting means for detecting an actual operational amount of said brake input means, and a deviation calculating means, coupled to said brake operational amount detecting means, for calculating a deviation between the detected actual operational amount and a preset reference operational amount of said brake input means.
Claim 4
Dependent Claim 132 words
An automatic steering system for a vehicle, comprising: a movement locus setting means for calculating a locus of movement of a vehicle to a target position, an actuator adapted to steer a wheel of the vehicle based upon the locus of movement set by said movement locus setting means, a brake input means operated by a driver to brake the vehicle, an actuator driving control means coupled to said actuator for operating said actuator when said brake input means is operated, a brake operational amount detecting means for detecting an actual operational amount of said brake input means, and a deviation calculating means, coupled to said brake operational amount detecting means, for calculating a deviation between the detected actual operational amount and a preset reference operational amount of said brake input means.
