Problems solved by technology

[0006] This last solution is indeed more advantageous, but this solution creates no change for other drivers, because once the driver accepts the new setting value, his vehicle decelerates to the speed limited by this new setting value, and then expects to drive at a speed limited by the new setting value The new speed is driven until the next signboard, the new speed is significantly less than the immediate speed limit, and other drivers cannot understand why

Embodiment Construction

[0024] The object of the invention is in particular to provide a speed regulation device DR for being able to regulate the speed of a vehicle V in the presence of variable speed restrictions.

[0025] In the following, as a non-limiting example, the vehicle V is considered to be of the motorized type. The vehicle is, for example, a sedan. However, the invention is not limited to this type of vehicle. The present invention relates to virtually any land vehicle that can travel on roads with variable speed limits. Accordingly, the present invention also relates, but without limitation, to road vehicles, motorcycles, buses, trucks.

[0026] Furthermore, in the following, as a non-limiting example, it is considered that the vehicle V comprises a powertrain GM of conventional type, ie comprising only an internal combustion engine MT as a source of torque. However, the vehicle may comprise a powertrain of the hybrid type, i.e. comprising at least one internal combustion engine and...

Abstract

The invention relates to a device (DR) which is responsible for controlling the speed of a vehicle (V) and includes processing means (MT) arranged, in response to the driver of the vehicle (V) validating a new speed limit that is to be observed from a known position and is lower than a current control speed, to trigger the application of a selected deceleration profile, suitable for lowering the current control speed to a new control speed that is no higher than the new speed limit substantially at this known position, between a first position, which is between a primary position of the vehicle (V) at a time at which the driver performs the aforementioned validation, and a second position at which the application of a maximum deceleration profile can be triggered at the latest, and this second position.

Description

technical field [0001] The invention optionally relates to vehicles of the motorized type, and more precisely to the automatic regulation of the speed of such vehicles. Background technique [0002] Some speed regulators provide functionality for informing the driver when there is a new speed limit, which is less than the detected immediate regulated speed, and proposing a new speed setpoint applicable to the new speed limit. The new speed limit is either obtained by reading a remote speed limit sign board by a computer installed in the front of the vehicle, stored in a map database in the vehicle, or transmitted via radio waves. If the driver accepts this new speed setpoint proposal, the driver presses a dedicated control member and the speed regulator immediately triggers the application of a deceleration, which is used to constrain the vehicle to the speed defined by the accepted new setpoint drive. [0003] The new speed limit is detected in front of the sign board, it...
