The pressure sensor arrays coupled to the handlebar grips actively monitor engagement of the rider with the vehicle, which includes appropriate handlebar grip and turn detection. The wheel speed sensors provide data related to a speed at which the rider of the vehicle is driving the vehicle or entering a corner. The gyroscope provides data on how a rider tilt is affecting a vehicle tilt. The accelerometer provides data related to acceleration of the vehicle. The sensor data comprises data from at least one of the pressure sensor arrays, the wheel speed sensors, the accelerometer and the gyroscope. The imaging and sensing unit 111 transmits at least one of the sensor data and the visual data related to the rider to the computing unit 101 using the communication network 109.

The computing unit 101 receives at least one of the sensor data and the visual data related to the rider from the imaging and sensing unit 111. Based on the at least one of the sensor data and the visual data, the computing unit 111 alerts the rider for safe riding. The computing unit 101 may be present on a server or in a navigation device of a vehicle or as an independent unit (or a device) coupled to the dashboard of the vehicle. The server may be a local server or on a cloud server. The computing unit 101 includes an I/O interface 103, a memory 105 and a processor 107. The I/O interface 103 is configured to communicate with the imaging and sensing unit 111. The I/O interface 103 may employ communication protocols/methods such as, without limitation, audio, analog, digital, monaural, Radio Corporation of America (RCA) connector, stereo, IEEE® 1394 high speed serial bus, serial bus, Universal Serial Bus (USB), infrared, Personal System/2 (PS/2) port, Bayonet Neill Concelman (BNC) connector, coaxial, component, composite, Digital Visual Interface (DVI), High Definition Multimedia Interface (HDMI®), Radio Frequency (RF) antennas, S Video, Video Graphics Array (VGA), IEEE® 802.11 b/g/n/x, Bluetooth, cellular e.g., Code Division Multiple Access (CDMA), High Speed Packet Access (HSPA+), Global System for Mobile communications (GSM®), Long Term Evolution (LTE®), Worldwide interoperability for Microwave access (WiMax®), or the like.

The memory 105 is communicatively coupled to the processor 107 of the computing unit 101. The memory 105, also, stores processor instructions which cause the processor 107 to execute the instructions for alerting the rider of the vehicle for safe riding.

The processor 107 may include at least one data processor for alerting the rider of the vehicle for safe riding.

In one embodiment, the imaging and sensing unit 111 together with the computing unit 101 form a system for alerting a rider of a vehicle for safe riding.

Hereafter, the operation of the computing unit 101 for alerting the rider of the vehicle for safe riding is described.

Situation 1 i.e. , a rider is taking a turn at a corner: when the rider is taking a turn, the computing unit 101 receives at least one of the sensor data and the visual data related to the rider from the imaging and sensing unit 111. The computing unit 101 determines an absolute lean angle of a posture of the rider based on at least one of the sensor data and the visual data. When the absolute lean angle exceeds the predetermined threshold angle, the computing unit 101 determines weight imbalance of the rider using the absolute lean angle and the sensor data. Thereafter, based on the determination of the weight imbalance, the computing unit 101 alerts the rider using at least one of an audio signal, a haptic signal and a visual signal for safe riding. Situation 2 i.e. , rider’s eyes showing drowsy or fatigue signs: when the rider is driving the vehicle, the computing unit 101 receives at least one of the sensor data and the visual data related to the rider from the imaging and sensing unit 111. The computing unit 101 determines an absolute lean angle of a posture of the rider based on at least one of the sensor data and the visual data. When the absolute lean angle does not exceed the predetermined threshold angle, the computing unit 101 continues with processing upcoming at least one of the sensor data and the visual data to monitor rider posture. Additionally, the computing unit 101 utilizes the visual data from the infrared camera received in the at least one of sensor data and visual data related to the rider to determine whether rider’s eye focus is on a road or rider’s eyes showing drowsy or fatigue signs. When rider’s eye focus is on the road or rider’s eyes showing no drowsy or fatigue signs, the computing unit 101 continues with processing upcoming at least one of the sensor data and the visual data to monitor rider posture. When rider’s eye focus is not on the road or rider’s eyes showing drowsy or fatigue signs, the computing unit 101 alerts the rider using at least one of an audio signal, a haptic signal and a visual signal for safe riding.

The computing unit 101 , in addition to the I/O interface 103 and the processor 107 described above, includes data 201 and one or more modules 211 , which are described herein in detail. In the embodiment, the data 201 is stored within the memory 105. The data 201 includes, for example, sensor data and visual data 203 and other data 205.

The sensor data and visual data 203 includes data from at least one of pressure sensor arrays, wheel speed sensors, an accelerometer and a gyroscope. The sensor data and visual data 203 receives data from the imaging and sensing unit 111.

The other data 205 may store data, including temporary data and temporary files, generated by one or more modules 211 for performing the various functions of the computing unit 101 . In the embodiment, the data 201 in the memory 105 is processed by the one or more modules 211 present within the memory 105 of computing unit 101. In the embodiment, the one or more modules 211 may be implemented as dedicated hardware units. As used herein, the term module refers to an Application Specific Integrated Circuit (ASIC), an electronic circuit, a Field Programmable Gate Arrays (FPGA), Programmable System on Chip (PSoC), a combinational logic circuit, and/or other suitable components that provide the described functionality. In some implementations, the one or more modules 211 are communicatively coupled to the processor 107 for performing one or more functions of the computing unit 101 . The one or more modules 211 when configured with the functionality defined in the present disclosure will result in a novel hardware.

In one implementation, the one or more modules 211 include, but are not limited to, a receiving module 213, a determining module 215 and an alerting module 217. The one or more modules 211 , also, include other modules 219 to perform various miscellaneous functionalities of the computing unit 101.

The receiving module 213 receives at least one of the sensor data and the visual data related to the rider from the imaging and sensing unit 111 through the I/O interface 103. The receiving module 213 further sends the at least one of the sensor data and the visual data to the determining module 215.

The determining module 215 determines absolute lean angle of a posture of the rider based on at least one of the sensor data and the visual data. In detail, the determining module 215 detects rider tilt movement using the visual data received in at least one of the sensor data and visual data. In one embodiment, the determining module 215, in addition to the visual data, utilizes the sensor data from wheel speed sensors, an accelerometer, and a gyroscope to make decision on rider tilt movement. The rider tilt movement is correlated and compared by the determining module 215 with at least one of the sensor data from pressure sensor arrays coupled to a seating unit of the vehicle and handlebar grips received in at least one of the sensor data and visual data. Based on the correlation and comparison, the determining module 215 determines absolute lean angle. Subsequently, the determining module 215 determines weight imbalance of the rider using the absolute lean angle and the sensor data when the absolute lean angle exceeds a predetermined threshold angle. In detail, the determining module 215 compares the absolute lean angle with the predetermined threshold angle. The predetermined threshold angle may be an angle defined as per industry standard for two wheeler or three wheeler vehicles. In one non-limiting embodiment, the absolute lean angle is 35°. When the absolute lean angle does not exceed the predetermined threshold angle, the determining module 215 continues with processing upcoming at least one of the sensor data and the visual data to monitor rider posture. When the absolute lean angle exceeds the predetermined threshold angle, the determining module 215 determines weight imbalance of the rider. For determining weight imbalance, the determining module 215 determines using the visual data whether the rider is leaning on a left side, on a right side or not leaning on either side. If there is no weight imbalance i.e. , the rider is not leaning on either side, the determining module 215 continues with processing upcoming at least one of the sensor data and the visual data to monitor rider posture. When the determining module 215 determines that the rider is leaning on the left side, the determining module 215 correlates the sensor data from pressure sensor arrays coupled to the seating unit of the vehicle and a left handlebar grip to determine weight imbalance of the rider. Analogously, when the determining module 215 determines that the rider is leaning on the right side, the determining module 215 correlates the sensor data from pressure sensor arrays coupled to the seating unit of the vehicle and a right handlebar grip to determine weight imbalance of the rider. The determining module 215 sends the determined weight imbalance of the rider to the alerting module 217.

In another embodiment, the determining module 215 utilizes visual data from the infrared camera received in the at least one of sensor data and visual data related to the rider to determine whether rider’s eye focus is on a road or rider’s eyes showing drowsy or fatigue signs. When rider’s eye focus is on the road or rider’s eyes showing no drowsy or fatigue signs, the determining module 215 continues with processing upcoming at least one of the sensor data and the visual data to monitor rider posture. When rider’s eye focus is not on the road or rider’s eyes showing drowsy or fatigue signs, the determining module 215 sends the determined rider’s eye focus imbalance of the rider to the alerting module 217.

The alerting module 217 alerts the rider for safe riding upon determination of the weight imbalance. The alerting module 217 alerts the rider using at least one of an audio signal, a haptic signal and a visual signal. For instance, the alerting module 217 alerts the rider if the rider is entering a corner with too much speed and/or bad posture that can affect centre of gravity of the vehicle, which can in turn lead to skidding.

In one embodiment, the alerting module 217 alerts the rider for safe riding upon determination of the rider’s eye focus imbalance. The alerting module 217 alerts the rider using at least one of an audio signal, a haptic signal and a visual signal.
