Problems solved by technology

[0006] However, existing control methods have certain disadvantages, since the driver's expressed desire by acting on the accelerator pedal is not always correctly interpreted; Positive and negative gradients of the road surface or the presence of wind) are fully taken into account, which may lead to the selection of an inappropriate transmission ratio

Embodiment Construction

[0027] exist figure 1 1 , a motor vehicle is generally indicated at 1 and includes an engine compartment 2 arranged at a front position and housing an internal combustion engine 3 . The internal combustion engine 3 includes a drive shaft 4 which transmits its movement to the front drive wheels 5 via a transmission 6 . The transmission mechanism 6 includes a servo-assisted clutch 7 arranged between the drive shaft 4 and a servo-assisted gearbox 8 through a differential (not shown) and counter axle (not shown) located therebetween. Instead, the output of the gearbox 8 is permanently connected to the front wheels 5 .

[0028] The motor vehicle 1 further comprises a passenger compartment 9, an acceleration control device 11 (in particular an accelerator pedal 11), a brake control device 12 (in particular a brake pedal 12) and an instrument panel 13, the passenger compartment 9 is provided with a driver's front seat and a steering wheel 10, and the instrument panel 13 includes a ...

Abstract

A cruise management method and device for a road vehicle (1), wherein the position of an accelerator control (11) is detected, a current speed (CS) of the vehicle (1) is detected and a current transmission ratio is detected; a desired speed (DS) is calculated as a function of the position of the accelerator control (11), the current speed (CS) of the vehicle (1) and the current transmission ratio and is used to control the drive torque generated by an engine (3) of the vehicle (1) and is displayed by a specific display instrument (16) disposed in a dashboard (13) of the vehicle (1).

Description

technical field [0001] The invention relates to a method and a device for managing cruising of a motor vehicle. Background technique [0002] Conventionally, the accelerator is directly mechanically connected by cable to the carburetor or fuel injection control system; in this case the driver has complete control over the drive torque produced by the engine and thus the speed of the vehicle control. [0003] A system called "dive by wire" has recently been proposed, in which the accelerator is connected to a position sensor which reads the position of the accelerator pedal and transmits this information to a control unit which, according to the The speed of the vehicle is regulated by the driver's expressed desire to act on the accelerator pedal and the drive torque produced by the engine essentially according to parameters depending on the vehicle's safety requirements, such as anti-skid and stability control. In other words, when a "fly-by-wire" system is used, the drive...
