Embodiment Construction

[0013] figure 1 A control system for a vehicle with which the invention may be used is schematically shown. The vehicle comprises a front axle 1 with steered wheels 2 , 3 , a rear propeller axle 4 with drive wheels 5 - 8 , and optionally a rear axle 9 with wheels 10 and 11 . Furthermore, the vehicle comprises an engine 13 connected to a gearbox 12 which drives a propeller shaft 4 by means of an output shaft 14 from the gearbox. The gearbox 12 and the motor 13 are controlled respectively via control units 15 , 16 which are controlled via a main control unit 17 . An engine management system (EMS) 16 controls the vehicle's motion functions, which may include, for example, fuel injection and motor-braking. The control is based on a number of input signals, which may include signals from a (not shown) throttle controller (position of the accelerator pedal), a speed sensor and a brake management system. The Gearbox Management System (GMS) 15 controls the shifting function, where,...

Abstract

A brake feedback system for a vehicle comprising a brake choice evaluation means arranged to evaluate the driver's choice of braking system, e.g. auxiliary brakes and service brake, by comparing the driver's use of at least one braking system, with a total use of the braking systems in the vehicle during a braking action, wherein the driver's use of at least one auxiliary brake system is determined based upon at least one brake power model of the at least one auxiliary brake system, and wherein the brake choice evaluation system is arranged to grade the driver's choice of braking system and to feedback recommendations about a preferred braking system and / or function to the driver on a presentation means.

Description

technical field [0001] The invention relates to a brake feedback system. Background technique [0002] When driving heavy vehicles such as trucks, buses, etc., vehicle economy has become an important factor when attempting to reduce costs in the business in which the vehicle is used. According to the acquisition cost of the vehicle, the largest expenditure items for the vehicle include fuel costs and maintenance costs. These costs are often correlated, meaning that a heavily used vehicle both consumes more fuel and suffers greater wear and tear, thus increasing maintenance costs. [0003] However, for companies that use heavy vehicles in their business, an existing problem is that it is difficult to determine how much fuel consumption and wear e.g. originate from inattentive driving, and how much originates from adverse traffic conditions, Examples include extremely undulating terrain and / or urban environments. [0004] The wear and tear experienced by a vehicle during in...
