Patent number: 10988033Abstract: A control system for a vehicle having a first wheel (101) arranged to be driven by a first drive source and a second wheel (101) arranged to be driven by a second drive source, wherein the first wheel and the second wheel are transversely located on the vehicle, the control system comprising a controller (102) and a monitoring device, wherein the monitoring device is arranged to monitor the power differential between the power being applied to the first wheel by the first drive source and the power being applied to the second wheel by the second drive source, wherein upon a determination that the power differential between the power being applied to the first wheel and the second wheel is greater than a predetermined value, the controller is arranged to reduce the power differential.Type: GrantFiled: September 20, 2016Date of Patent: April 27, 2021Assignee: PROTEAN ELECTRIC LIMITEDInventors: Helen Monkhouse, Richard Thomas Burke, Christopher David Hilton

Patent number: 9431939Abstract: An electric motor or generator system comprising a rotor having a first set of magnet poles; a stator having a first sensor mounted on the stator and a second sensor mounted in substantially a diametrically opposite position on the stator relative to the first sensor, wherein the first sensor is arranged to output a first signal indicative of a first rotor flux angle associated with the first set of magnet poles as the rotor rotates relative to the stator and the second sensor is arranged to output a second signal indicative of a second rotor flux angle associated with the first set of magnet poles as the rotor rotates relative to the stator; and means arranged to determine a corrected rotor flux angle by averaging the first rotor flux angle indicated by the first sensor and the second rotor flux angle indicated by the second sensor.Type: GrantFiled: October 3, 2012Date of Patent: August 30, 2016Assignee: PROTEAN ELECTRIC LIMITEDInventor: Richard Thomas Burke
