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 present invention is in particular to provide a speed regulating device DR for being able to regulate the speed of the vehicle V in the presence of a variable speed limit.
[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. But the invention is not limited to this type of vehicle. The present invention relates to virtually any land vehicle that can be driven on a road with variable speed limits. Accordingly, the present invention is equally but not limited to road vehicles, motorcycles, buses, trucks.
[0026] Furthermore, in the following, as a non-limiting example, the vehicle V is considered to comprise a powertrain GM of a conventional type, ie comprising only an internal combustion engine MT as a torque source. However, the vehicle may comprise a powertrain of a hybrid type, ie comprising at least one internal combustion engine and at least one auxi...

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 present 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 notifying the driver when there is a new speed limit (the new speed limit being less than the detected immediate adjusted speed) and proposing a new speed setpoint suitable for the new speed limit. The new speed limit is obtained either by reading a remote speed limit indicator panel by a computer installed in the front of the vehicle, or stored in a map database in the vehicle, or transmitted via radio waves. If the driver accepts the proposal for this new speed setpoint, the driver presses the dedicated control member and the speed regulator immediately triggers the application of deceleration, which is used to restrain the vehicle at the speed limited by the accepted new setpoint drive. [0003] The new speed limit is d...
