Abstract

A brake system (400) for a heavy vehicle, the brake system comprising: a first brake controller (WEM1) arranged to control braking on a left wheel (120l) of a front axle (101); and a second brake controller (WEM2) arranged to control braking on the right wheel (120r) of the front axle (101) wherein the first brake controller and the second brake controller are connected by a backup connection (220), the spare connection is arranged to allow one of the first brake controller and the second brake controller to undertake brake control of a wheel of the other of the first brake controller and the second brake controller. The brake system (400) comprises a first brake controller (WEM3) arranged to control braking on the left wheel (140l) of the first rear axle (102), and a second brake controller (WEM4) arranged to control braking on the left wheel (140l) of the second rear axle (102). And a fourth brake controller (WEM4) arranged to control braking on the first rear axle (102) right wheel (140r), where the third brake controller (WEM3) and the fourth brake controller (WEM4) are arranged to place the respective rear axle left wheel and rear axle right wheel in an unbraked state in response to a fault, whereby the third brake controller (WEM3) and the fourth brake controller (WEM4) control braking on the first rear axle (102) right wheel (140r). The third brake controller and the fourth brake controller are arranged as brake controllers that do not react after failure.

Description

technical field [0001] The present disclosure relates to redundancy in braking systems for heavy-duty vehicles. The present disclosure is particularly relevant to vehicles configured for autonomous driving. The present invention can be applied to heavy vehicles such as trucks and construction equipment. Although the present invention will be described primarily with respect to cargo transport vehicles such as semi-trailers and trucks, the present invention is not limited to this particular type of vehicle, but may also be used in other types of vehicles, such as passenger cars. Background technique [0002] The braking system of a heavy vehicle is critical to safe vehicle operation. The braking system not only limits the speed of the vehicle when needed, but also plays an important role in maintaining the stability of the vehicle. Therefore, heavy vehicles with faulty brake systems represent a significant risk. It is desirable to minimize this risk. [0003] To ensure t...
