A system for automatically actuating the parking brake on a vehicle

Abstract

The present invention concerns a system (100) for automatically actuating the parking brake (300) on a vehicle, such as a truck (200), comprising a parking brake (300) and at least a driver's door lock (400). Said system (100) comprises means for applying said parking brake (300) to an active position as a response to at least said driver's door lock (400) being locked in an active position. Preferably, said system comprises lock response means (110) which is operable for at least providing a first signal indicating that at least said driver's door lock (400) is locked in an active position; and hold means (120) for actuating the parking brake (300) to an active position based on said first signal. Thus, it is no longer necessary for a driver to remember to actuate the parking brake, when he or she parks the vehicle, as long as at least the driver's door lock on the vehicle is locked. By the invention, it has been realized that the manual locking action of the driver's door lock may be further utilized for automatic actuation of the parking brake, i.e. the same manual action may induce two separate functions at the same time. Further, it has been realized that the system is increasing the effect of the locking the vehicle door by effectively locking the wheels of the vehicle when the parking brake is on, which further reduces the possibility of a vehicle thief removing said vehicle, e.g. by towing it away. As a consequence, the system may be perceived to further provide an improved anti-theft device.

Description

technical field [0001] The present invention relates to a system for automatically actuating a parking brake on a vehicle comprising a parking brake, such as a truck. The present aspect can be applied to various types of vehicles, such as trucks, buses, trailers, farm vehicles, construction vehicles, off-road vehicles, but also passenger cars, airport vehicles and the like. Background technique [0002] A safety problem encountered with vehicles, especially large vehicles or vehicles transporting heavy equipment or goods, is that when the vehicle is stopped, if the driver does not activate or actuate the parking brake for some reason, the vehicle may be damaged. There are various reasons why a driver forgets to activate the parking brake, and if the ground supporting said vehicle has a slope of even a small angle, it can lead to a situation where the vehicle becomes "rollaway", i.e. the vehicle moves away from its resting position. And cause damage to personnel, damage to b...

This improves the safety of cabinet vehicles, making it impossible to drive with the cabinet open, but does not solve the problem for parked vehicles with the engine not running
