Vehicle driving aid apparatus
First Claim
1. A vehicle driving aid apparatus comprising:
- a steering mechanism, wherein a relationship between a steering angle of a steering wheel and a turning angle of turning wheels is arbitrarily set;
a wakefulness determination part for determining wakefulness of a driver;
an alarm controller that controls an alarm for awaking the driver when the wakefulness determination part determines a reduction of the wakefulness of the driver; and
a turning controller for suspending the steering wheel from controlling the turning wheels and controlling the turning angle of the turning wheels independently of the steering angle of the steering wheel at least when the alarm controller controls the alarm.

Abstract
A steering mechanism 1 is configured as a steering mechanism which allows an arbitrary relationship to be set between a steering mechanism unit 2 through which steering of a driver is input and a turning mechanism unit 3 for turning wheels 5, 5 to be turned, those units being controlled by an ECU 30 on a steer-by-wire basis. When alarm control to wake up the driver is performed according to a determination indicating a reduction of the wakefulness of the driver, the ECU 30 suspends the steer-by-wire control to control the turning mechanism unit 3 independently of the steering mechanism unit 2. As a result, even when an improper steering input is provided by the driver who is at a low level of wakefulness, it is possible to prevent such mis-steering from being reflected in driving.

11. A vehicle driving aid apparatus comprising:
-
a steering mechanism for turning wheels at a turning angle corresponding to a steering angle of a steering wheel, a relationship between the steering angle of the steering wheel and the turning angle being arbitrarily set; a determination part for determining driver'"'"'s concentration to the driving the vehicle; an alarm controller for controlling an alarm to concentrate the driver on driving the vehicle when the determination part determines a reduction of the driver'"'"'s concentration to the driving the vehicle; and a turning controller suspending the steering wheel from controlling the turning wheels and for controlling the turning angle of the turning wheels independently of the steering angle of the steering wheel at least when the alarm controller controls the alarm. - View Dependent Claims (12, 13, 18, 19)
