Description:TECHNICAL FIELD
[0001] The present subject matter generally relates to a saddle type vehicle. The present subject matter specifically, but not exclusively, relates to the disposition of Micro-Electronic Mechanical Systems (MEMS) in a saddle type vehicle.

BACKGROUND
[0002] A conventional saddle type vehicle generally comprises of an internal combustion engine, and various electronic components including an electronic security device. Various components are mounted at different locations in the vehicle. The placement of those components like the 10 electronic security device plays an important role, especially in saddle type vehicles where space utilization is of vital significance. The disposition of any Micro-Electronic Mechanical Systems (MEMS) at a secured location so that the Micro-Electronic Mechanical Systems (MEMS) is enabled to accurately determine the movement status of the vehicle is critically 15 important. Micro-Electronic Mechanical Systems (MEMS) are a hybrid of mechanical and electrical components which are compact and take a shape similar to a microchip.
[0003] Moreover, it is important that such Micro-Electronic Mechanical Systems (MEMS) are easily accessible to increase the efficiency in servicing 20 such Micro-Electronic Mechanical Systems (MEMS).
[0004] Making arrangements for Micro-Electronic Mechanical Systems (MEMS) is necessary and thus, it is desired that the Micro-Electronic Mechanical Systems (MEMS) is placed in such a location which ensures its performance is not affected by surrounding metallic parts and components. 25 Exposure of the Micro-Electronic Mechanical Systems (MEMS) to plurality of vibrating metallic parts and components may lead to inaccurate readings and incorrect movement status of the vehicle, further endangering the safety of the user.
[0005] Further, the Micro-Electronic Mechanical Systems (MEMS) can be 30 exposed to dust, dirt, and water ingress, and prone to stagnant issues resulting

in malfunctioning of the system. Apart from this, the Micro-Electronic Mechanical Systems (MEMS) should be placed in a location which is easily serviceable, accessible to a user, and easy to assemble. Apart from this, there is a need to mount the Micro-Electronic Mechanical Systems (MEMS) compactly at a secured location. 5
[0006] With the advancement in technology, Micro-Electronic Mechanical Systems (MEMS) incorporates an inertial measurement unit. The inertial measurement unit (IMU) uses a Micro-Electronic Mechanical Systems technology, and incorporates gyroscopes and accelerometers. The IMU is used to accurately measure both acceleration in a linear direction and changes 10 in orientation. An inertial measurement unit works by detecting linear acceleration using one or more accelerometers and rotational rate using one or more gyroscopes. One of the disadvantages of IMUs is that they typically suffer from accumulated error, therefore, it is critically important that the IMU is disposed in a location which enables the IMU to read the vehicle 15 related parameters accurately and in a precise manner.
[0007] IMUs (Inertial Measurement Unit) are typically used to manoeuvre vehicles. IMU (Inertial Measurement Unit) is sensor which senses the vehicle yaw, pitch and roll movements and acceleration exerted on vehicle in directions of three axes orthogonal to one another. In vehicles, IMUs can be 20 integrated into vehicle tracking systems, giving the system a dead reckoning capability and the ability to gather as much accurate data as possible about the vehicle's current speed, turn rate, heading, inclination and acceleration, in combination with the vehicle's wheel speed sensor output and, if available, reverse gear signal, for purposes such as better traffic collision analysis. It 25 thus provides signal to a controller of the vehicle to take the necessary actions. IMU inputs are also used for different functions such as Anti-lock braking and other advanced features of the ABS.
[0008] However, existing vehicles have the IMU sensors located either below the battery box, close to the ground, thereby making such location of IMU 30 sensors prone to nearby direct water wash and mud splashing from below. This affects the functionality of the IMU sensor to properly detect the vehicle

related parameters and to take necessary actions to properly manoeuvre the vehicle. Moreover, since it is located to nearby vibrating components of the vehicle such as engine, and battery box which dissipates vibration and heat, such IMU sensor is prone to interfere with high voltage cables, vibrations, and magnetic interferences. 5
[0009] Moreover, IMUs must be assembled and disposed in a vehicle such that there is reduction in sensor errors due to mechanical environment solicitations and to protect sensors as they can be damaged by shocks or vibrations.
[00010] Moreover, the IMU sensors are used in Motorcycle Stability Control 10 Systems, Semi-active Damping Control Systems or other Systems in a vehicle. The IMU is configured to measure angular rates and accelerations of the vehicle. Due to the measuring principles used by the sensors in the IMU, disruptive vibrations with high amplitude or vibrations that are in a critical frequency range that interfere with the IMU, is likely to cause disturbance of 15 the sensor signals. Therefore, it is essential to limit the translational and rotational motion at the location of the IMU unit, and the only changes that the IMU sensor is subjected to should be the vehicle’s movement status and dynamic motion.
[00011] Furthermore, it is necessary that the mounting of the IMU sensor be 20 made such that there is no misalignment of brackets and variation of the brackets should not lead to inaccurate measurements of the vehicle’s dynamic motion.
[00012] In conventional vehicles, the location of the IMU sensor is placed in the front or rear plane of the vehicle, which leads to the IMU sensor reading 25 incorrect vehicle related parameters. IMU sensors are also used for safety mechanisms related to braking, therefore, such incorrect interpretations of the vehicle related parameters may lead to a dangerous situation of the user.
[00013] Therefore, there is a need to locate and dispose the Micro-Electronic Mechanical Systems (MEMS) such as the IMU unit to enable accurate and 30 precise judgement of the vehicle dynamic motion, also enabling an ease of accessibility and serviceability of such systems.
