Problems solved by technology

However, sensors for detecting whether the driver's seat is vacant are generally not a standard component in motor vehicles and implementing this known warning system would be quite expensive
Also, existing sensors of this type are often not very reliable and may cause annoying warning signals during operation, or may not generate a warning signal when the driver leaves the vehicle without engaging the parking brake

Embodiment Construction

[0027] figure 1 A motor vehicle 1 in the form of a tractor is schematically shown in . The vehicle 1 has a pneumatic parking brake circuit comprising a plurality of brake cylinders 20, one for each wheel 2 locked by the parking brake. figure 1 Only the brake cylinder 20 of one of the wheels 2 is shown. The reciprocating push rod 21 protruding from the brake cylinder 20 is operatively connected to the brake device 3, and is used to support the wheel 2 without rotating when the push rod 21 moves axially to the forward position, and when the push rod 21 moves axially Used to release the wheels for turning when in the retracted position. Brake cylinder 20 is of conventional design and in figure 2A longitudinal section is shown in . Counter to the action of the compression spring 22, the push rod 21 is axially movable from the advanced position to the retracted position. The parking brake is engaged under the action of the compression spring 22 and is released using compresse...

Abstract

The invention relates to a warning system and a method for alerting a driver of a vehicle that the parking brake of the vehicle is not engaged, wherein a warning perceivable in the vehicle cabin is generated when the following conditions, optionally in combination with one or several further conditions, are simultaneously fulfilled: it is established that the ignition of the vehicle is on, it is established that the driver access door of the vehicle cabin is open, it is established that no throttle lever, clutch lever or brake lever of the vehicle is activated, it is established that the gear shift lever of the vehicle is in the neutral position or that the gear shift lever of the vehicle is not in the reverse gear position, and it is established that the parking brake is not engaged.

Description

technical field [0001] The invention relates to a warning system for a motor vehicle equipped with a parking brake, wherein said system comprises a warning device adapted to generate an alarm under certain predetermined conditions to warn the driver that the parking brake is not engaged. The invention also relates to a method for warning a driver of a vehicle that the parking brake of the vehicle is not engaged. Furthermore, the invention relates to a computer program comprising computer program code for implementing such a method, a computer program product comprising a data storage medium readable by an electronic control unit and having such a computer program stored thereon, and an electronic control unit. Background technique [0002] When a vehicle is parked on an incline, if the driver of the vehicle forgets to engage or fails to engage the vehicle's parking brake properly before exiting, the vehicle may begin to roll away under its own weight. Such unexpected situa...
