摘要
An electrohydraulic vehicle power braking system for a passenger car driving autonomously on public roads. Two power brake pressure generators are provided which are independent of one another, one of which preferably includes an electromechanically drivable power piston-cylinder unit, and the other preferably includes two hydraulic pumps. Each power brake pressure generator includes a brake fluid reservoir, which is divided into chambers and which together are connected to a further brake fluid reservoir, which is not divided into chambers. The further brake fluid reservoir includes a brake fluid sensor, with the aid of which a brake fluid loss due to a leak at any arbitrary point of the vehicle power braking system is establishable. Due to short lines, the brake fluid reservoirs cause low flow resistances, and thus a rapid brake pressure build-up, even when the brake fluid is cold and, as a result, viscous.
