Patent number: 10500905Abstract: A control valve assembly that includes: an inlet for receiving compressed air from a supply line; an outlet for supplying compressed air to a transfer line; and a control valve for selectively placing the inlet in fluid communication with the outlet. The control valve assembly is configured to be removably disposed in a wheel hub.

Patent number: 10399392Abstract: A processor for controlling operation of a central tire inflation system (CTIS) to change a tire pressure of a tire of a vehicle is configured to control the CTIS to inflate or deflate the tire to a predetermined tire pressure which is above a target tire pressure for the tire. The processor then controls the CTIS to deflate the tire until the target tire pressure is reached. In this manner, a second tire inflation operation to achieve the target tire pressure in the tire can be avoided.Type: GrantFiled: April 10, 2015Date of Patent: September 3, 2019Assignee: JAGUAR LAND ROVER LIMITEDInventors: Paul King, Emma-Claire Dunning, Robbie Lesbirel, Maelle Dodu, Thuy-Yung Tran, Laur Läänemets, Jonathan Woodley

Patent number: 10173478Abstract: A filter device for a conduit includes a gas-permeable pre-filter element and a gas-permeable, liquid-impermeable filter element. The filter device is configured to be fluidly coupled to a conduit such that a gas can flow, in sequence, through the pre-filter element, the filter element and then the conduit. The filter device can be used in each of a vehicle hollow driveshaft and a hollow wheel stub axle forming a CV joint having a compressed air supply line which passes therethrough. Compressed air can be supplied via the air supply line without the need for an additional fluid transfer device fluidly connecting the driveshaft and the stub axle's conduits.Type: GrantFiled: September 12, 2014Date of Patent: January 8, 2019Assignee: Jaguar Land Rover LimitedInventors: Emma-Claire Dunning, Edward Hoare, Laur Läänemets, Maelle Dodu, Thuy-Yung Tran

Patent number: 10099518Abstract: A processor for controlling operation of a central tire inflation system. The processor controls the central tire inflation system to inflate a vehicle tire from a current tire pressure to a target tire pressure. The processor is configured to generate one or more output signals to cause the central tire inflation system to supply compressed air to inflate the tire from said current tire pressure to the target tire pressure in at least first and second stages. In the first stage, the central tire inflation system supplies compressed air to inflate the tire from the current tire pressure to an intermediate tire pressure. In the second stage, the central tire inflation system supplies compressed air to inflate the tire from the intermediate tire pressure to the target tire pressure. The first and second stages of the inflation are discrete from each other.Type: GrantFiled: April 10, 2015Date of Patent: October 16, 2018Assignee: Jaguar Land Rover LimitedInventors: Paul King, Emma-Claire Dunning, Robbie Lesbirel, Maelle Dodu, Thuy-Yung Tran

Publication number: 20180207999Abstract: A central tire inflation system (CTIS) of a vehicle (VH) for supplying compressed air to a tire of the vehicle to compensate for air loss from the tire. The CTIS determines a rate of air loss from the tire and includes both a sensor arranged to measure a temperature of a compressor of the CTIS and an electronic control unit (ECU) configured to: compare the rate of air loss with a rate of air loss threshold, determine, based on the compressor temperature and the comparison of the rate of air loss with the rate of air loss threshold, whether the CTIS can support compensation for the air loss; and control the CTIS to supply compressed air to the tire to compensate for the air loss if the CTIS can support compensation for the air loss.Type: ApplicationFiled: July 14, 2016Publication date: July 26, 2018Inventors: Emma-Claire DUNNING, Paul KING, Robbie LESBIREL, Maelle DODU, Thuy-Yung TRAN

Publication number: 20180170124Abstract: A control valve assembly for use with a vehicle wheel assembly. The control valve assembly includes: an inlet for receiving compressed air from a supply line; an outlet for supplying compressed air to a transfer line; and a control valve for selectively placing the inlet in fluid communication with the outlet. The control valve assembly is configured to be removably disposed in a wheel hub. The control valve assembly also includes an annular cage mounted around the outlet. The annular cage supports a transfer line filter for filtering air moving between the control valve and the transfer line. The cage has a base ring and a secondary ring. The transfer line filter extends intermediate the base and secondary rings. The base and secondary rings each have a radial foot arranged to space the transfer line filter from the control valve assembly to provide an annular cavity therebetween.Type: ApplicationFiled: June 9, 2016Publication date: June 21, 2018Inventors: Maelle DODU, Emma-Claire DUNNING, Robbie LESBIREL

Patent number: 9989102Abstract: A vented gaiter (6) for mounting to a shaft (4) comprises: a rim (34) defining an opening (33) for receiving the shaft (4); and a separate venting element (40). The venting element (40) is disposed within said opening (33). The shaft (4) is received in the opening (33), and the rim (34) is mounted to the shaft by means of a circular clamp (22). The venting element (40) is thus retained in place between the shaft (4) and the rim (34) and allows any air accumulated inside a CV joint enclosure (28) formed by the gaiter (6) when the gaiter (6) is mounted to the shaft (4) to vent axially according to a direction substantially parallel to the shaft longitudinal axis. The venting element (40) comprises a gas-permeable liquid-impermeable membrane (41).Type: GrantFiled: September 12, 2014Date of Patent: June 5, 2018Assignee: Jaguar Land Rover LimitedInventors: Emma-Claire Dunning, Edward Hoare, Laur Läänemets, Maelle Dodu, Thuy-Yung Tran

Patent number: 9884522Abstract: A central tire inflation system for a tire. The system includes one or more pneumatic control valves for controlling inflation of a respective tire. A first compressed air source is provided for supplying compressed air to inflate the tire. A second compressed air source is provided for supplying compressed air to control the at one or more pneumatic control valves. A control means is provided for controlling the supply of compressed air from the second compressed air source to generate a pneumatic control signal to control the one or more pneumatic control valves. The first compressed air source can be a compressor configured to provide compressed air to inflate the tires.
