Embodiment Construction

[0030] figure 1 is a block diagram of an exemplary vehicle system 100 . System 100 includes vehicle 105, which is a land vehicle such as an automobile, truck, or the like. The vehicle 105 includes a computer 110 , vehicle sensors 115 , actuators 120 for actuating various vehicle components 125 , and a vehicle communication module 130 . Communication module 130 allows computer 110 to communicate with server 145 via network 135 .

[0031] Computer 110 includes a processor and memory. The memory includes one or more forms of computer-readable media and stores instructions executable by the computer 110 to perform various operations, including operations as disclosed herein.

[0032] The computer 110 can operate the vehicle 105 in an autonomous mode, a semi-autonomous mode, or a non-autonomous (manual) mode. For the purposes of this disclosure, autonomous mode is defined as a mode in which each of vehicle 105 propulsion, braking, and steering is controlled by computer 110; in ...

Abstract

The invention provides a solenoid valve diagnostic system. The system can include a solenoid manifold including a plurality of solenoid valves to control fluid flow between a tube and a plurality of nozzles, wherein one end of the tube is connected to a pump and the other end of the tube is connected to an inlet of the solenoid manifold; and a controller programmed to determine whether at least one solenoid valve of the plurality of solenoid valves is incorrectly in an open position based on pressure measurements representing a fluid pressure within the tube.

Description

technical field [0001] The present disclosure generally relates to vehicle sensors. Background technique [0002] Vehicles such as autonomous or semi-autonomous vehicles often include various sensors. Several sensors detect the internal state of the vehicle, such as wheel speed, wheel orientation, and engine and transmission variables. Some sensors detect the position or orientation of the vehicle, such as Global Positioning System (GPS) sensors; accelerometers, such as piezoelectric or microelectromechanical systems (MEMS); gyroscopes, such as rate gyroscopes, ring laser gyroscopes, or fiber optic gyroscopes; inertial measurement unit (IMU); and magnetometer. Some sensors detect the outside world, such as radar sensors, scanning laser rangefinders, light detection and ranging (LIDAR / lidar) devices, and image processing sensors such as cameras. A lidar device detects the distance to an object by emitting pulses of laser light and measuring the time-of-flight of the pulses...
