Patent number: 5924505Abstract: The invention concerns a driving system for a hybrid-powered motor vehicle. It includes a generator set producing a direct current used by a driving set with an electric motor for driving at least one driving wheel of the vehicle. Using an accelerator, the driver gives a power set-point signal that is used by a first adjusting device which acts on the thermal engine, the generator, and the AC/DC converter of the generator set. A second adjusting device adjusts the power of the driving set as a slave of the generator set, according to the variations in the voltage of the supply circuit with respect to a desired voltage, without considering the signal from the accelerator.Type: GrantFiled: January 3, 1997Date of Patent: July 20, 1999Assignee: SMH Management Services AGInventors: Patrick Theurillat, Gianni Francescutto, Robert Apter, Rene Jeanneret, Antoine Toth

Patent number: 5653302Abstract: The vehicle comprises an electric drive motor, a generator driven by a gasoline engine and a regulating circuit which regulates the speed of rotation of the gasoline engine and the electric power supplied to the electric motor as a function of the position of an accelerator pedal and which is arranged so that this electric power increases at the same time as the speed of rotation of the gasoline engine when the pedal is actuated to increase the speed of the vehicle. This feature removes the delay which, in known vehicles of the same type, separates the actuation of the accelerator pedal from the increase in the electric power supplied to the drive motor.Type: GrantFiled: April 18, 1995Date of Patent: August 5, 1997Assignee: SMH Management Services AGInventors: Thomas Edye, Rene Jeanneret

Patent number: 5632352Abstract: The vehicle (1) comprises a driving wheel (2) driven by an electric motor (3) whose control circuit (4) is supplied by a generator (6) coupled to a fuel engine (5), and a sensor (18) supplying a power-setting control signal (SC) representative of the position of an accelerator pedal (17) and hence of the desired power that the electric motor (3) has to supply to the wheel (2). To avoid having to provide the vehicle (1) with a large capacity traction battery, the vehicle further comprises means (7, 14 to 16, 19, 20) responsive to the power setting signal (SC) to regulate the rotational speed of the fuel engine (5) to the value at which the latter supplies a mechanical power (Pm) that is equal, firstly, to the desired power and, secondly, to a predetermined fraction of its maximum power.Type: GrantFiled: March 21, 1995Date of Patent: May 27, 1997Assignee: SMH Management Services AGInventors: Rene Jeanneret, Thomas Edye, Jacques Muller

Patent number: 5573312Abstract: A vehicle (31) has a composite braking system (electric and mechanical). This composite braking system having asynchronous electric motors (4a to 4d) associated with the wheels (2a to 2d) and a mechanical braking device having a hydraulic circuit (14) and mechanical brakes (18a to 18d). The composite braking system also has an electronic measuring device (36) connected to rotation frequency sensors (34a to 34d) disposed on each of the wheels, this electronic device supplying a reference signal to the control circuit (6) of the asynchronous electric motors which regulate the stator frequency of these motors as a function of the value of the reference signal. The braking system of the invention is anti-locking and very effective in any driving situation.Type: GrantFiled: May 18, 1994Date of Patent: November 12, 1996Assignee: SMH Management Services AGInventors: Jacques Muller, Rene Jeanneret, Antoine Toth

Patent number: 5432418Abstract: The invention concerns a motor system of an electric type vehicle, comprising at least two asynchronous electric motors (M1, M2) supplied in parallel by a central electric supply. This central electric supply is controlled by a control device supplying thereto a first control signal (SCF) determining the value of the supply frequency (FAL) and a second control signal (SCA) determining the value of the supply amplitude (UAL) of the supply voltage. These first and second control signals are regulated essentially in dependence upon a signal (SMI) which is a measurement of the principal supply current (IAL), an instruction signal (SCS) and a signal (SFMX) representing the maximum value of the rotational frequency of the rotors (R2, R2) of said motors.Type: GrantFiled: June 30, 1993Date of Patent: July 11, 1995Assignee: SMH Management Services AGInventor: Rene Jeanneret

Patent number: 5412305Abstract: A charging apparatus comprising discrete charging circuits each for connection to a different group of cells of an accumulator having multiple groups of cells. Each discrete charging circuit comprises a separate transformer the primary winding of which is connected to a source of an a.c. voltage common to all discrete charging circuits. The secondary winding of each transformer is connected to the input of a rectifier whose output is connected to charging terminals for connection to group terminals of a corresponding group of cells. This arrangement enables the accumulator to be completely charged while substantially reducing the risk of damaging the cell or cells of lowermost maximum capacity.Type: GrantFiled: May 28, 1993Date of Patent: May 2, 1995Assignee: SMH Management Services AGInventor: Rene Jeanneret

Patent number: 5408169Abstract: A control device for an asynchronous motor (2), notably intended for the drive system of an electric vehicle, comprises electric supply source (10) able to produce an AC supply voltage whose frequency (FAL) and amplitude (UAL) may be adjusted independently of one another. For a given frequency of the supply voltage, the amplitude of the voltage is able to vary between a minimum value and a maximum value, the difference between the frequency of rotation of the turning magnetic field in the vicinity of the rotor and the frequency of rotation of the rotor being maintained substantially constant as long as the amplitude of the supply voltage is less than the maximum value. Once the maximum value has been reached, the torque on the shaft of motor (2) is increased by increasing the slip.Type: GrantFiled: June 22, 1993Date of Patent: April 18, 1995Assignee: SMH Management Services AGInventor: Rene Jeanneret

Patent number: 5402046Abstract: The vehicle drive system has an asynchronous motor mechanically coupled to a wheel of the vehicle, a rechargeable accumulator, a first converter interposed between the rechargeable accumulator and the motor and arranged so as to regulate the electric power supplied to the motor and a generator driven by an internal combustion engine, as well as a control circuit. To make it possible to recharge the accumulator under optimum conditions, the system also has a second converter arranged so as to regulate the power supplied by the generator to the accumulator and to the first converter.Type: GrantFiled: June 25, 1993Date of Patent: March 28, 1995Assignee: SMH Management Services AGInventor: Rene Jeanneret

Patent number: 4320635Abstract: The device includes a canal having a narrowing entry and a widening outlet, separated by the poles of a pair of opposing electromagnets, and in which selective means, or selectors, are shifted. Two substantially identical, geometrically and magnetically symmetrical selector stations are provided. The entry and the outlet of the canal include a magnetic adherance system, functioning alternately as a stabilizer and as an amplifier of movement, following the direction of the device shifting in relation to the selectors to be selected.Type: GrantFiled: June 4, 1979Date of Patent: March 23, 1982Assignee: Edouard Dubied & Cie.

Patent number: 4250233Abstract: A tubular plate comprising oval tubes aligned parallel to one another, each containing two spaced grid rods of a corrosion-resistant lead alloy as current conductors. The rods of the individual tubes are joined to form a grid having a connecting part at the top. Near the bottom, each two lead rods are connected by a crosspiece.Type: GrantFiled: February 19, 1980Date of Patent: February 10, 1981Assignee: Leclanche S.A.Inventor: Rene Jeanneret
