The device (7) has speed clamping units (700) predefining an authorized maximal forward motion speed i.e. clamping speed. The clamping units are configured for intercepting signals emitted by a control member (40) of regulator and/or limiter (501). The cla...

It is an object to provide a vehicle travel control device that can adjusts a vehicle velocity without giving an uncomfortable feeling to a driver even when a target velocity is a very low velocity such as few kilometers per hour. An ECU designates a value...

A constant speed control method for a vehicle and a device thereof are disclosed. The constant speed control method includes steps of: firstly examining if a constant speed switch of the vehicle is pressed by an electronic control unit; allowing the electr...

In order to improve a response to a sensitivity of an accelerator pedal of a motor vehicle and a sudden acceleration of the vehicle, width of an insensitive zone provided in a vicinity of a portion of a first logic pattern for auto-cruise control, in which...

Fuel consumption due to abrupt acceleration is reduced. An auto-cruising control (6) is automatically started without intention of a driver and executes a control for gently and reasonably accelerating a vehicle even when an accelerator pedal is displaced ...

A method for monitoring an electronically controlled drive unit of a vehicle uses actual vehicle acceleration and a preselected vehicle acceleration. Actual acceleration is determined from any of an acceleration sensor (50) or vehicle speed sensors (30,32)...
