The term "scanning" refers to an object, surface or a part of a body to be traversed by a detector. The term "scanning rate" shall therefore refer to an occurrence of an object, surface or part of a body is being transverse by a detector.

Referring to FIG. 1 which shows a system block diagram of a power management system 100 for a motor vehicle in accordance with a preferred embodiment, the power management system 100 includes at least one sensing device 102, 102' from a vehicle application system. An example of a vehicle application system may be an onboard vehicle application system or an interior vehicle system 106, for collecting sensing signals from a passenger cabin of a motor vehicle. An example of such an interior vehicle system 106 maybe a driver monitoring system. The at least one sensing device 102'may also be collecting sensing signals for an exterior vehicle system 108. An example of an exterior vehicle system 108 maybe a surround-view camera, which include at least one sensing device 102' such as LiDar or radar to monitor a condition of an environment surrounding a motor vehicle implemented with such an exterior vehicle system 108. Ina preferred embodiment, the least one sensing device 102 of the interior vehicle system 106 may also collect sensing signals in relation to an operator 112 within the motor vehicle. By way of an example, the at least one sensing device 102 maybe a biometric sensor of an interior vehicle system 106 embedded within a passenger cabin.

The power management system 100 further includes a processing unit 104, to determine the state of the operator 110 according to the sensing signals received from the at least one sensing device 102. The state of the operator 110 may be determined by the processing unit 104 within the power management system 100. In an alternative embodiment, the state 110' of the operator 112 is processed and determined by a processing unit that is external to the power management system 100 and electronically communicated to the power management system 100. In the context of a motor vehicle, suitable communication protocol for transmitting and receiving data information between different vehicle systems may include controller area network (CAN bus), Local Interconnect Network (LIN) or FlexRay.

The processing unit 104 functions as a computing system and may include a memory for storing a set of instructions. The processing unit 104 is used to execute the set of instructions which is stored in memory, to switch at least one of a vehicle system 106, 108 of the motor vehicle to a power saving mode corresponding to the state 110 of the operator 112 determined in accordance with the sensing signals collected by at least one of the sensing devices 102, 102'. Amain advantage of the aforesaid configuration yields 5 a power saving management system 100 for a motor vehicle which executes a corresponding power saving mode in accordance with the state 110 of the operator determined. In particular, the state 110 of the operator determined is related to a mood or an emotion of the operator 112, thus adjustment of the vehicle systems 106, 10 108 will cater to the specific requirements of the operator 112 in response to the operator's emotion or mood.

Referring now to FIG. 2A, which shows flowchart 200a illustrating a method of managing power of a motor vehicle in accordance with this disclosure, at step 202, a processing unit 104 of a power management system 100 receives sensing signals from at least one sensing device 102, 102'. At step 204, the processing unit 104 determines a state of the operator in accordance with the sensing signals received from step 202. In a next step 206, the processing unit 104 initiates a decision on a power saving mode corresponding to a state of the operator determined from step 204. In one embodiment, in response to the state of the operator determined to be angry and/or exhausted, the processing unit 104 at step 208, executes an instruction to carry out a power saving mode, by switching a scanning rate of the at least one sensing device 102, 102' to a high occurrence mode. By switching the scanning rate to a high occurrence mode, a frequency of sensing signals from the at least one sensing device 102, 102' being received by the processing unit 104 of the power management system 100 is increased. In this manner, power distribution is allocated to at least one vehicle system that addresses the needs of the state of the operator. With a scanning rate of the at least one sensing device 102, 102' switched to high occurrence mode, the steps 202, 204 and 206 are repeated until the state of the operator is determined to be normalized. In the event the state 110 of the operator 112 is neutral, the processing unit 104 executes an instruction to carry out a power saving mode at step 214, by switching the scanning rate of the at least one sensing device 102, 102' to a default occurrence mode.

In an exemplary embodiment referred to as exemplary embodiment 1 shown in FIG. 3, when the state of the operator is determined to be angry and/or exhausted, the processing unit 104 may execute an instruction to carry out a power saving mode to switch a scanning rate of at least one sensing device 102' of an exterior vehicle system 108 from a default occurrence mode or a low occurrence mode to high occurrence mode. In this scenario, an example of an exterior vehicle system 108 may be a surround-view camera system. Preferably, the processing unit 104 may execute an instruction to carry out a cower saving mode, b'y adjusting a heating, ventilation, and air conditioning (HVAC) system to adjust an ambient temperature, to increase comfort of the operator 112. More preferably, the processing unit 104 may further execute an instruction to play soothing music, for example classical music, jazz music, country music, opera and/or other suitable genres deemed suitable for managing the operator's emotion or mood. In certain embodiments, the feature of soothing music is a playlist preselected by the operator. Even more preferably, the processing unit 104 may further adjust a lighting system of a passenger cabin of the motor vehicle, to change the ambient of the passenger cabin. To increase a safety of the operator 112, the power management system 100 may execute an instruction to a vehicle function system to control at least one vehicular automation function of the motor vehicle. An example of the at least one vehicular automation function may be an autonomous driving function mode.

In one embodiment as shown in FIG. 2B of flowchart 200b, an input sensing signal from at least one sensing device 102, 102' is received at step 202. A state of the operator determined at step 204, in response to sensing signals received from step 202. At step 206, the processing unit 104 initiates a decision on a power saving mode corresponding to the state of operator determined from step 204. In the event the state of the operator is determined to be happy and/or refresh, the processing unit 104 of the power management system 100 executes step 210, switching a scanning rate of at least one of a sensing device 102 of an interior vehicle system 106 to a low occurrence mode. Advantageously, by switching at least one vehicle system which does not requires intensive scanning rate at the moment where the operator 112 is happy and/or refreshed, an overall power consumption rate is reduced.

In an exemplary embodiment referred to as exemplary embodiment 2 shown in FIG. 3, when the state of the operator is determined to be happy and/or refreshed, the processing unit 104 maintains a scanning rate of the at least one sensing device 102 of an interior vehicle system 106 at a default mode or no change. However, a scanning rate of the at least one sensing device 102' of the exterior vehicle system 108 is switched to low occurrence mode, if the scanning rate is at a default mode or a high occurrence mode, thereby reducing power consumption.

Consequently, efficiency of power management is achieved, in response to the state of the operator.

FIG. 2C shows a flowchart 200c in accordance with one embodiment, an input of sensing signals from at least one sensing device 102, 102' is received by a power management system 100 as disclosed herein, and a state of an operator is determined at step 204. At step 206, a decision is made by the processing unit 104, in response to the state of operator determined at step 204. If the state of the operator is determined as neutral, the processing unit 104 executes an instruction to switch a scanning rate of the at least one sensing device 102, 102', 102" of the at least one vehicle system 106, 108, 114 from a high occurrence mode or a low occurrence mode to a default occurrence mode. As shown in FIG. 3 under exemplary embodiment 3, in response to the state of the operator determined to be neutral, the interior vehicle system 106, exterior vehicle system 108 and the vehicle function system 114 is switched to default mode at step 212. With a continuous scanning of information by the at least one sensing device 102 of the interior vehicle system 106, the steps 202, 204 and 206 are repeated and in the event the state of the operator is determined to be neutral, the processing unit 104 executes instructions to switch the scanning rate to a default occurrence mode, i.e., step 212 as shown in FIG. 2C.

Turning now to FIG. 2D which shows a flowchart 200d in accordance with an exemplary embodiment, the at least one sensing device 102, 102' and 102" are already operating at a default occurrence mode. In response to the state of the operator determined to be neutral at step 204, the processing unit 104 decides and execute instructions to maintain a scanning rate of the at least one sensing device 102, 102', 102" at a default occurrence mode at step 214.

For clarity and brevity, determination of state of operator may be based upon sensing signals received from driver monitoring system, biometric sensors, microphones or any other suitable sensing devices implemented in interior vehicle system 106. In certain embodiments, further analysis, for example speech recognition or analysis of operator's images may be required at step 204 to determine state of operator. It shall be understood by a skilled practitioner, Thus, it can be seen, a power management system operable to distribute power consumption of a motor vehicle in response to a state of an operator has been provided. [call out additional advantages] While exemplary embodiments have been presented in the foregoing detailed description of the disclosure, it should be appreciated that a vast number of variation exist.
