Description:FIELD OF THE INVENTION
[001] The present invention generally relates to a rotary electrical machine. More particularly, the present invention relates to a rotary electrical machine for a vehicle and a method for performing vehicle control thereof.

BACKGROUND OF THE INVENTION
[002] Conventionally, a vehicle having a power unit is operated through a central vehicle ECU (Electronic control unit). The ECU is configured to provide inputs during starting and stopping operation of a vehicle upon receiving an electric start or ignition key input from a user of the vehicle. However, in certain conventional vehicles, the ECU is unable to provide the starting and stopping inputs to a vehicle during an idling condition of the vehicle due to inadequate power supply from a generator or a power source of the vehicle. In existing vehicles, in order to provide optimum starting and stopping inputs to the vehicle during an idling condition, an integrated starter generator (ISG) machine is provided in the vehicle configured to communicate with the ECU. A dedicated ISG Controller is also provided alongside the ISG to communicate with the ECU. Generally, the idling conditions of the vehicle include a vehicle starting condition, a vehicle stopping condition such as during traffic or sudden braking of the vehicle to take a phone call etc. The ISG machine and the ISG controller determines a starting and stopping event of the vehicle and provide an input to the ECU to either give input to a fuel injector to start the vehicle or cut off supply of fuel or power to a vehicle power unit to stop the vehicle.
[003] However, during continuous riding condition of the vehicle, due to multiple idling conditions occurring at different intervals of time, the ISG machine experiences high temperature fluctuations during its operation. In certain circumstances, due to multiple starting and stopping inputs provided by the ISG machine and the ISG controller, the overall temperature of the ISG machine increases beyond a threshold temperature. At such high temperatures, the ISG machine becomes incapable of operating. There also arises the risk of explosion of the ISG machine.
[004] In contrast, if the vehicle is operating under cold conditions, say less than 20o Celsius, the ISG machine is unable to reach the optimum temperature to rotate and thereafter start the vehicle. Thus, in such situations the user keeps on providing inputs through the ignition key or the electric start switch to start the vehicle, but the ISG machine is unable to rotate as the ISG machine is unable to reach suitable operating temperature. This in turn damages the ignition key or the electric switch and affects the overall startability of the vehicle. Thus, a configuration for determining the actual temperature of the ISG is required.
[005] In previous attempts for gauging the temperature of the ISG for optimum operation, the ISG machine is connected to a vehicle temperature sensor to determine the temperature of the ISG machine. However, the vehicle temperature sensor reads the vehicle temperature and the ISG machine temperature at the same time which leads to error in determining the accurate temperature of the vehicle and the ISG machine.
[006] Thus, there is a need in the art for a rotary electrical machine for a vehicle, and a method of performing vehicle control thereof which addresses at least the aforementioned problems.

DETAILED DESCRIPTION OF THE INVENTION
[024] The present invention relates to a rotary electrical machine. In particular, the present invention relates to a rotary electrical machine for a vehicle and a method for performing vehicle control thereof.
[025] Figure 1 and Figure 2 illustrate a rotary electrical machine 100 for a vehicle 10. As illustrated, the rotary electrical machine 100 comprises a stator 110. The stator 110 has a plurality of teeth 112. In an embodiment, the plurality of teeth 112 extend radially outward from a core of the stator 110. The plurality of teeth 112 are configured to receive a plurality of stator coils 114. Herein, the plurality of stator coils 114 are wound depending on power rating and required efficiency of the rotary electrical machine 100, and the plurality of stator coils 114 are configured for allowing current to flow through as required.
[026] The rotary electrical machine 100 further comprises a rotor 120, and the rotor 120 is configured to be rotatably engaged with the stator 110. In an embodiment, the rotor 120 is disposed radially outwardly from the stator 110. Herein, provision of current to the stator coils 114 causes the rotor 120 to rotate, and conversely rotation of the rotor 120 through an external means induces the flow of current in stator coils 114. In an embodiment, the rotary electrical machine 100 is an Integrated Stater Generator of the vehicle. The Integrated Starter Generator, specifically the rotor 120 is operably connected to an internal combustion engine 160 (shown in Figure 3) of the vehicle 10. The Integrated Starter Generator is configured to receive power from a power source of the vehicle 10, thereby causing rotation of the rotor 120 for cranking of the internal combustion engine 160. Once the internal combustion engine 160 is cranked, the rotation of the rotor 120 by the internal combustion engine 160 allows for the Integrated Starter Generator to act as a generator for at least charging the power source of the vehicle 10 and provide electrical power to other vehicle parts as required.
[027] As further illustrated in Figure 1, the rotary electrical machine 100 comprises a sensor 130 that is provided in the rotary electrical machine 100. Herein, the sensor 130 is provided on the inside of the rotary electric machine 100. In other words, the sensor 130 is provided on an inner part of the rotary electrical machine 100. More specifically, the sensor 130 is provided on an inner part of the rotary electrical machine 100 and away from an outer casing of the rotary electrical machine 100. Herein, the sensor 130 is configured for sensing at least one operating parameter of the rotary electrical machine 100. In an embodiment, the at least one operating parameter comprises a temperature of the rotary electrical machine 100, and the sensor 130 is configured for sensing the temperature of the rotary electrical machine 100. The provision of the sensor 130 on the inner part of the rotary electrical machine 100 ensures that the sensor 130 is able to gauge the temperature of the rotary electrical machine 100 with accuracy. Further, provision of a dedicated sensor 130 for gauging temperature of the rotary electrical machine 100 also eliminates error or confusion in the measurement of the temperature of the rotary electrical machine 100. In an embodiment, the sensor 130 for gauging the temperature of the rotary electrical machine 100 includes one of but not limited to an oil-based sensor, a P-type sensor and an N-type sensor.
[028] Further, in the present invention, the sensor 130 is communicatively connected with an electronic control unit 140 (shown in Figure 3). Herein, the electronic control unit 140 is configured to receive the at least one operating parameter of the rotary electrical machine 100 from the sensor 130. The electronic control unit 140 is further configured to control an amount of electrical power supplied from the power source of the vehicle 10 to the rotary electrical machine 100 based on the at least one operating parameter received from the sensor 130.
[029] As illustrated in the embodiment depicted in Figure 1, the sensor 130 is placed on one of the plurality of teeth 112 of the stator 110. As illustrated in the alternative embodiment depicted in Figure 2, the sensor 130 is positioned between the plurality of teeth 112 of the stator 110. By virtue of such arrangement, the sensor 130 is specifically configured for gauging the temperature of the stator coils 114 of the rotary electrical machine 100, which is then communicated to the electronic control unit 140 as explained hereinbefore.
[030] In another alternate embodiment of the present invention, the rotary electrical machine 100 comprises an air gap between the stator 110 and the rotor 120, wherein the sensor 130 is positioned in the air gap of the rotary electrical machine 100. Such a positioning of the sensor 130 allows for a compact packaging of the rotary electrical machine 100.
[031] In another aspect, the present invention relates to the vehicle 10. As illustrated in Figure 3, the vehicle 10 comprises the rotary electrical machine 100. The rotary electric machine 100 comprises the stator 110 with the plurality of teeth 112 and the plurality of teeth 112 are configured to receive the plurality of stator coils 114. The rotary electric machine 100 further has the rotor 120 that is configured to be rotatably engaged with the stator 110. The rotary electric machine 100 further comprises a sensor 130 provided in the rotary electrical machine 100. Herein, the sensor 130 is configured for sensing at least one operating parameter of the rotary electrical machine 100.
[032] The vehicle 10 further comprises an electronic control unit 140. Herein, the electronic control unit 140 is in communication with the rotary electrical machine 100 via a machine controller 150. The electronic control unit 140 is configured to receive the at least one operating parameter of the rotary electrical machine 100 from the sensor 130. Further, the electronic control unit 140 is configured to control the amount of electrical power supplied from the power source of the vehicle 10 to the rotary electrical machine 100 based on the at least one operating parameter received from the sensor 130.
[033] As mentioned hereinbefore, in an embodiment, the rotary electrical machine 100 comprises the Integrated Starter Generator operatively coupled to the internal combustion engine 160 of the vehicle 10. In that, the ISG is configured to receive electrical power from the power source of the vehicle 10 and provide torque to the internal combustion engine 160 for cranking. Further, when the internal combustion engine 160 is cranked, the ISG is configured to receive torque from the internal combustion engine 160 and provide electrical power to the power source of the vehicle 10 for charging of the power source of the vehicle 10.
[034] In an embodiment, the at least one operating parameter comprises a temperature of the rotary electrical machine 100, and therefore, the sensor 130 is configured for sensing the temperature of the rotary electrical machine 100.
[035] In an embodiment, the electronic control unit 140 is configured to determine the temperature of rotary electrical machine 100 being higher or lower than or equal to a predetermined temperature. If the electronic control unit 140 determines the temperature of the rotary electrical machine 100 to be higher than the predetermined temperature, the electronic control unit 140 is configured to communicate with the machine controller 150 to cease the supply of electrical power to the rotary electrical machine 100, thereby disabling cranking of the internal combustion engine 160. The ceasing of the supply of electrical power to the rotary electrical machine 100 when the rotary electrical machine 100 is at a temperature higher than the predetermined temperature prevents the rotary electric machine 100 from inoperably high temperatures, thus protecting the rotary electric machine 100 from a failure and reduces the risk of explosion.
[036] On the contrary, if the electronic control unit 140 determines the temperature of the rotary electrical machine 100 to be lower than or equal to the predetermined temperature, the electronic control unit 140 is configured to communicate with the machine controller 150 and an Engine Management System Electronic Control Unit (EMS-ECU) 170 for controlling the rotary electrical machine 100 and the internal combustion engine 160 for cranking and stopping of the internal combustion engine 160. The electronic control unit 140 controls the rotary electrical machine 100 via the machine controller 150 and the EMS-ECU 170 controls the internal combustion engine 160 in synergy to perform the required start-stop operations. Thus, the electronic control unit 140 is configured such that the electronic control unit 140 allows for normal operation of rotary electrical machine 100 only when the temperature of the rotary electrical machine 100 is lower than or equal to the predetermined temperature. This ensures that the rotary electrical machine 100 remains in an optimum temperature range and is capable of providing cranking torque to the internal combustion engine 160 under repeated start-stop operations.
[037] In an embodiment, if the electronic control unit 140 determines the temperature of the rotary electrical machine 100 to be higher than the predetermined temperature, the electronic control unit 140 is configured to regulate and reduce the amount of electrical power supplied from the power source to the rotary electrical machine 100. The regulation and reduction of the amount of electrical power being supplied from the power source to the rotary electrical machine 100 ensures that the temperature of the rotary electrical machine 100 is not raised further, preventing failure of the rotary electrical machine 100.
[038] On similar lines, if the electronic control unit 140 determines the temperature of the rotary electrical machine 100 to be lower than or equal to the predetermined temperature, the electronic control unit 140 is configured to enable the full supply of electrical power from the power source to the rotary electrical machine 100. This ensures that maximum voltage is being supplied to the rotary electrical machine 100 for cranking of the internal combustion engine 160, especially under repeated start-stop operations, thus ensuring optimum output from the rotary electric machine 100 for cranking the internal combustion engine 160.
[039] In another aspect, the present invention relates to a method 300 for performing vehicle control for the vehicle 10. In that, Figure 4 illustrates the method steps involved in the method 300 for vehicle control. As illustrated, at step 302, if an ignition key is in an ON state is determined by the electronic control unit 140. If the ignition key is in ON state, the method 300 moves to step 304. Thereafter, at step 304, at least one operating parameter of rotary electrical machine 100 are received by the electronic control unit from the sensor 130. Thereafter, at step 306, the amount of electrical power supplied from a power source of the vehicle to the rotary electrical machine (100) is controlled by the electronic control unit 140 through a machine controller 150, based on the at least one operating parameter received from the sensor 130.
[040] In an embodiment, the rotary electrical machine 100 is an Integrated Starter Generator operatively coupled to an internal combustion engine 160 of the vehicle, and the operating parameter comprises a temperature of the rotary electrical machine 100.
[041] In an embodiment, the steps involved in performing vehicle control of the vehicle 10 are illustrated as method 400 in Figure 5. At step 402, the temperature of the rotary electric machine 100 is received by the electronic control unit 140. If at step 404, the temperature of the rotary electrical machine 100 is determined to be higher than the predetermined temperature by the electronic control unit 140, the method 400 moves to step 406. At step 406, cranking of the internal combustion engine 160 of the vehicle is disabled by the electronic control unit 140. If at step 404, the temperature of the rotary electrical machine 100 is determined to be lower than or equal to the predetermined temperature by the electronic control unit 140, the method 400 moves to step 408. At step 408, the temperature of the rotary electrical machine 100 is communicated by the electronic control unit 140, to the machine controller 150 and the Engine Management System Electronic Control Unit (EMS-ECU) 170. Thereafter, at step 410, the rotary electrical machine 100 and the internal combustion engine 160 are controlled by the electronic control unit 140, for cranking and stopping of the internal combustion engine 160.
[042] In an embodiment, the steps involved in performing vehicle control of the vehicle 10 are illustrated as method steps 500 in Figure 6. At step 502, the temperature of the rotary electric machine 100 is received by the electronic control unit 140. If at step 504, the temperature of the rotary electrical machine 100 is determined to be higher than the predetermined temperature by the electronic control unit 140, the method 500 moves to step 506. At step 506, the amount of electrical power supplied from the power source to the rotary electrical machine 100 is regulated and reduced, by the electronic control unit 140. If at step 504, the temperature of the rotary electrical machine 100 is determined to be lower than or equal to the predetermined temperature by the electronic control unit 140, the method 500 moves to step 508. At step 508, the full supply of electrical power from the power source to the rotary electrical machine 100 is enabled by the electronic control unit 140 thus ensuring optimum performance of the rotary electrical machine 100.
[043] Advantageously, the present invention provides for a rotary electrical machine for a vehicle wherein the sensor is placed on the inner part of the rotary electric machine. The provision of the sensor specifically for measuring the temperature of the rotary electric machine allows for accurate measurement of the temperature of the rotary electric machine, which is then used by the electronic control unit for controlling the supply of power to the rotary electrical machine. This also eliminates the requirement of any external circuitry for determining the temperature of the rotary electrical machine.
[044] Further, the present invention ensures that when the temperature of the rotary electrical machine is higher than the predetermined temperature, the power supplied to the rotary electrical machine is either ceased, or regulated and correspondingly reduced so as to ensure no further rise in the temperature of the rotary electrical machine. This prevents the rotary electrical machine from failure due to high temperatures and lowers risk of explosion. Further, startability issues faced by the vehicle due to high temperature of the rotary electric machine are also eliminated, since the rotary electric machine is always maintained below the predetermined temperature. This ensures that the rotary electric machine does not become incapable of operation, as the rotary electric machine might be when subjected to inoperably high temperatures. Further, the present invention also ensures that the rotary electric machine operates at full capacity only when the temperature of the rotary electric machine is lower than or equal to the predetermined temperature.
[045] Furthermore, the present invention also reduces the chances of potential damage to the ignition key and other vehicle components.
[046] While the present invention has been described with respect to certain embodiments, it will be apparent to those skilled in the art that various changes and modification may be made without departing from the scope of the invention as defined in the following claims.
