System And Method To Detect Accumulator Loss Of Precharge
US Patent:
2013029, Nov 7, 2013
Filed:
May 7, 2012
Appl. No.:
13/465392
Inventors:
Heng Zhou - Edwards IL, US
Assignee:
CATERPILLAR, INC. - Peoria IL
International Classification:
F17D 5/02
US Classification:
137 1511, 137551
Abstract:
Methods and apparatus for detecting a leak in a gas precharged hydraulic accumulator having an initial gas charge entail activating a hydraulic pump to charge the gas precharged hydraulic accumulator and the hydraulic circuit associated with the gas precharged hydraulic accumulator when the hydraulic circuit and the hydraulic accumulator have a temperature that is substantially equivalent to an ambient temperature, e.g., on a cold start. The hydraulic pressure in the hydraulic circuit is monitored, and when a step in the hydraulic pressure is detected, various quantities are measured and used to determine a volumetric efficiency of the pump for use in later calculations of remaining gas amount.
Methods To Detect Lateral Control Oscillations In Vehicle Behavior
US Patent:
2020016, May 28, 2020
Filed:
Nov 28, 2018
Appl. No.:
16/202673
Inventors:
- Detroit MI, US
Donald G. Wirkner - Dexter, US
Heng Zhou - Canton MI, US

Heng Zhou - Canton MI, US
International Classification:
B60W 30/02
G05D 1/00
G05D 1/00
Abstract:
An exemplary method for detecting a lateral oscillation of a vehicle includes monitoring yaw rate data and lateral acceleration data of the vehicle, analyzing the yaw rate and lateral acceleration data to generate a yaw rate signal energy distribution and a lateral acceleration signal energy distribution, determining whether a series of conditions are satisfied; and if the conditions are satisfied, automatically controlling the actuator to reduce the lateral oscillation of the vehicle. In some examples, the series of conditions includes the detection of spikes in the yaw rate and lateral acceleration data at approximately the same frequency, a magnitude of the spikes exceeding a first threshold, and a phase shift between the yaw rate and lateral acceleration data exceeding a second threshold.
