Embodiment Construction

[0009] figure 1 A non-limiting example of an open loop brake control system 10 is shown, hereinafter referred to as system 10 . In general, system 10 is adapted for use with an automated vehicle, such as host vehicle 12 . As used herein, the term "automated vehicle" may apply to instances where host vehicle 12 is operating in automated mode 14 (i.e., a fully automated mode) in which the operator (not shown) of host vehicle 12 does nothing other than designate a destination. Any other operations that run the host vehicle 12 . However, full automation is not required. It is contemplated that the teachings presented herein may be used in situations where the host vehicle 12 is operating in a manual mode 16 where the degree or level of automation may be such that the brakes are automatically applied to avoid collisions and / or during traffic jams in which vehicles are closely spaced. Or control the host vehicle 12 to move forward.

Abstract

An open-loop braking control system (10) suitable for automated vehicles includes a braking unit (26) and a controller (32). The brake unit (26) is used to vary brake pressure (28) to operate brakes (30) of a host vehicle (12). The controller (32) is in communication with the braking unit (26). The controller (32) operates the braking unit (26) to an initial pressure (34) to initiate braking of the host vehicle (12) according to a braking model (36): the braking model (36) is based on the brakes (30 ) to characterize the relationship between vehicle deceleration rate (38)-initial pressure (34).

Description

technical field [0001] The present invention generally relates to a braking control system, and more particularly to a system for operating a braking unit to an initial pressure to brake a host vehicle according to a braking model that applies brakes to the vehicle based on the operating time of the brakes. The brake deceleration rate-initial pressure relationship was characterized. Background technique [0002] It has been found that for a given value of brake pressure, ie, the hydraulic pressure of the fluid in the brake system, the braking force or vehicle deceleration response produced by the brake system of the same vehicle can vary. That is, under a given brake pressure, the degree to which the vehicle decelerates varies. For example, it has been found that under certain conditions, heated brakes stop faster than cooled brakes, but overheated brakes stop more slowly than heated brakes. For automated vehicles, this inconsistency can create unpleasant fluctuations in d...
