Auto-drive control unit for vehicles
First Claim
1. An auto-drive control unit for a vehicle comprising:
- (a) running control means for performing auto-drive to control speed and steering angle of the vehicle based on detection signals from a plurality of sensors,(b) changeover means for switching between the auto-drive and manual drive,(c) evaluation means for evaluating running stability of the vehicle while running when the steering angle is within a given range and substantially in a neutral state, and(d) mode control means for prohibiting changeover from the auto-drive to the manual drive by said changeover means when the vehicle running is evaluated to be in an unstable state by said evaluation means.

Abstract
A unit for smoothly switching from auto-drive to manual drive for a vehicle provided with an auto-drive mode. To perform auto-drive, an auto-drive ECU controls steering wheel, brake, and accelerator actuators in accordance with signals from a route recognition/obstruction check sensor, a GPS and the like. When an interface (switch) for switching to the manual drive is operated, the auto-drive ECU evaluates running stability/instability in accordance with signals from various running safety devices and sensors for detecting a variation in vehicle state, and if the vehicle is in an instable state, prohibits a shift to the manual drive, even when the vehicle is running on a straight road.
