Patent number: 8935029Abstract: The invention relates to a device and a method for cooling an electricity storage means, in particular a high-capacity battery (110), said device comprising: cooling means (130) for cooling said storage means; a “low voltage” battery (120); means (130), supplied with power by the low voltage battery (120), for increasing the rate of cooling of the storage means (110). The invention also relates to a vehicle (100), especially a motor vehicle, comprising such a device, said vehicle comprising an electric power train (220).Type: GrantFiled: July 13, 2011Date of Patent: January 13, 2015Assignee: Peugeot Citroën Automobiles SAInventors: Julien Sabrie, Stephane Rimaux, Thomas Cadilhac

Patent number: 8473137Abstract: The invention relates to a method for managing a hybrid vehicle air conditioning system that includes a compressor (8) generating coolness that is storable in a cold reserve (10), the heat engine having access to a control (34) that automatically controls the starting and stopping thereof. Said management method is characterized in that it has the power needed to pull the vehicle (6) and a level of coolness in the cold reserve (10) such that: when the heat engine (2) is on, the stopping (82) thereof is enabled if the charge level (92) in the cold reserve (10) is greater than a minimum threshold and the necessary pulling power is below a maximum threshold, both of said thresholds correlating with each other; and when the heat engine (2) is off, a command for the starting (84) of said heat engine is made if the charge level of the cold reserve (10) is less than a maximum threshold and the necessary pulling power is above a minimum threshold, both of said thresholds also correlating with each other.Type: GrantFiled: July 7, 2010Date of Patent: June 25, 2013Assignee: Peugeot Citroen Automobiles SAInventors: Thomas Sourioux, Stephane Rimaux

Patent number: 7826940Abstract: The invention essentially concerns a method for fast starting on an up slope or with a high load. Said method uses a power transmission device (1.1) comprising a traction chain. Said traction chain consists in particular of a heat engine (2), a clutch (3), an electrical macine (4), and wheels (6). The invention is characterized in that while the vehicle is stopped or is running at low speed up a slope, the heat engine (2) is stopped, and when the vehicle is accelerated, the heat engine (2) is started using a starting system (7) mechanically independent of the electrical machine.Type: GrantFiled: February 24, 2006Date of Patent: November 2, 2010Assignee: Peugeot Citroen Automobiles SAInventors: Paulo Miranda, Stephane Rimaux

Patent number: 7766108Abstract: The invention essentially concerns a method for fast starting of a hybrid vehicle. Said method uses a power transmission device (1.1) comprising a traction chain consisting of a heat engine (2), a clutch (3), an electrical machine (4), and wheels (6). The invention is characterized in that said method, in order to rapidly accelerate the vehicle when it is stopped, consists in starting the heat engine (2) concurrently with the actuation of the electrical machine, using a starting system (7) mechanically independent of the electrical machine (4).Type: GrantFiled: February 24, 2006Date of Patent: August 3, 2010Assignee: Peugeot Citroen Automobiles SAInventors: Stephane Rimaux, Paulo Miranda

Patent number: 7584040Abstract: The following steps are performed in the control method: determining a mode of operation from amongst a permanent mode and a transient mode, as a function of a set of variables comprising said estimated values; correcting the value of the speed of rotation of the outlet shaft in such a manner that: if the mode has been determined as being the permanent mode, then the moving average (L?) of the gear ratio (L) over a period (T) of a plurality of unit time intervals lies between a first threshold value (S1) that is negative and a second threshold value (S2) that is positive; and if the mode has been determined as being the transient mode, then said moving average (L?) of the gear ratio (L) lies outside the range of values defined by the first and second threshold value (S1, S2).Type: GrantFiled: February 3, 2004Date of Patent: September 1, 2009Assignee: Peugeot Citroen Automobiles SAInventor: Stéphane Rimaux

Publication number: 20080245332Abstract: The invention concerns a method applicable to a motor vehicle parallel hybrid drive train, comprising a heat engine, at least one electrical machine, a variable speed ratio transmission member, a first clutch linking the heat engine to the electrical machine, and a second clutch linking the transmission member to the electrical machine or to the heat engine. The method includes the following successive steps which consist in: a) placing the first clutch in open position; b) after positioning the second clutch in slip control, powering the electrical machine so as to drive same with kinetic energy higher than the energy required for starting the heat engine; and c) closing the first clutch so as to transmit, from the electrical machine to the heat engine, an energy at least sufficient to compensate the resisting torque of the heat engine shaft, and drive same at a starting speed.Type: ApplicationFiled: October 9, 2006Publication date: October 9, 2008Applicant: PEUGEOT CITROEN AUTOMOBILES SAInventors: Stephane Rimaux, Janette Rimaux
