Method For Providing A Pressure Point For A Haptic Gas Pedal Of A Hybrid Vehicle

Abstract

A system and method for controlling a hybrid vehicle having an electric operating mode selectively modify a pressure point for an accelerator pedal in response to current vehicle and / or ambient operating conditions to reduce unintentional starting of an internal combustion engine and maintain electric mode operation while the accelerator pedal position is less than the pressure point. The vehicle operating conditions or mode may indicate a parking maneuver, stop-and-go traffic, or an eco mode where electric operation may be desired.

Description

technical field [0001] The invention relates to a method for setting the pressure point of a tactile accelerator pedal of a hybrid vehicle. Background technique [0002] It is known from the prior art to provide, when a certain position of the accelerator pedal of a motor vehicle is reached, a pressure point which can be felt by the operator of the accelerator pedal, which can be overcome by applying greater force, after which Trigger an action in the vehicle. Such a pressure point is implemented, for example, as a mechanical pressure point, for example as a downshift switch for an automatic transmission. Such a downshift switch is usually a mechanical part which is located at the end of the actuation stroke for the accelerator pedal and provides the corresponding shift points there which follow the pressure on the operator's foot. increase is evident. [0003] Vehicles that include different types of drive systems that propel the vehicle in combination or individually ut...

AI Technical Summary

Problems solved by technology

This can happen even if activation of the internal combustion engine can be avoided due to a sufficiently high state of charge of the on-board battery and / or traffic conditions

Inadvertent activation of the internal combustion engine leads to undesired additional fuel consumption, perceived poor and irregular handling and unnecessary exhaust emissions

In certain application situations which are also often still susceptible to misinterpretation of accelerator pedal movements carried out by the operator, for example when the vehicle is parked, unintentional activation of the internal combustion engine can pose an undesired hazard
