Embodiment Construction

[0029] A vehicle equipped with a hill-start assist device according to the invention comprises an engine block, an assisted parking brake 5, a bus 4 on which signals are transmitted from the rest of the vehicle 6, and a computer controlling the engine block.

[0030] Bus 4 is preferably CAN-compliant TM (Control LAN for Control Area Network) Standard bus.

[0031] The engine block includes a heat engine coupled to the drive wheels through a transmission device including a gearbox and clutches that can be controlled by the user or by a computer, depending on the type of gearbox.

[0032] As a variant, the engine block may comprise one or more electric motors with or without heat engines.

[0033] Said hill start aid cooperates with a computer 1 for controlling a parking brake 5 , which computer is also connected to the bus 4 .

[0034] The computer 1 is equipped, as is known, with means for generating commands to apply or release the assisted parking brake 5 , the commands fo...

Abstract

The invention relates to a control assist method for a vehicle including a power train connected to the drive wheels by a clutch. The invention is characterised in that it involves a clutch curve which connects the position of the clutch pedal and a maximum torque that can be transmitted by the corresponding clutch, as a function of the reliability thereof, said reliability being lower when the vehicle is first used and increasing with the use of the vehicle.

Description

technical field [0001] The invention relates to an assistance method for the control of a vehicle with a manual or automatic gearbox, which method applies a clutch profile learning algorithm. [0002] The invention relates in particular to a hill start assist method and apparatus, but is also applicable to the estimation of clutch wear of a vehicle, or the control of an electronic traction control system (more commonly known as Electronic Traction Control ETC) of a 4x4 vehicle. Background technique [0003] In some vehicles, automakers propose an assisted parking brake. [0004] This assisted parking brake should be a valuable addition to customers, as it is more expensive than conventional parking brake solutions. [0005] In order to make the system more valuable, some manufacturers have therefore decided to add a hill-start assist function, especially to assist starting (or driving off) on a slope. The principle is that once the torque transmitted by the engine to the dr...
