Description

[0001] TITLE OF INVENTION

[0002] SYSTEM FOR SELECTIVELY OPERATING REGENERATIVE BRAKING IN VEHICLE AND METHOD THEREOF

[0003] FIELD OF THE INVENTION

[0004]

[0001] The present invention generally relates to regenerative braking, more particularly, relates to a system for selectively operating regenerative braking in a vehicle.

[0005] BACKGROUND OF THE INVENTION

[0006]

[0002] In regenerative braking mechanism, an electric traction motor uses a vehicle's momentum to recover energy that would otherwise be lost to the brake discs as heat energy. In existing electric or hybrid electric vehicles, regeneration is performed whenever the vehicle is braked or when throttle is stopped. Based on the route of the vehicle or the trip planned by the user and the terrain during the trip, a high regenerative current or a low regenerative current will be required. For instance, a downward slope of the vehicle may result in higher stopping distance even if the regenerative current is more, however, a plain road may result in shorter stopping distance, if the regenerative current is high. The existing systems do not have any means for adjusting the amount of regeneration.

[0007]

[0003] In existing vehicles, the lack of customization of regenerative braking poses a significant disadvantage to users. Without the ability to adjust regeneration levels through a user interface, riders are left with a fixed setting that may not suit their preferences or riding conditions. This limitation can result in discomfort during driving experiences, particularly in situations where aggressive braking is undesirable or when maximizing energy recovery is necessary.

[0008]

[0004] Further, energy recovery during regeneration occurs at a fixed value of current determined by the battery's charge current demand, without providing users the option to customize this regeneration process through an instrument cluster of the vehicle. Consequently, customers are unable to adjust the regeneration level to a lower mode, which would help mitigate aggressive braking on long stretches of road or in slippery conditions. Further, customers are also unable to adjust the regeneration level to a higher mode, which would help them recover maximum energy from regeneration. This lack of customization can lead to discomfort in the driving experience for the customer.

[0009]

[0005] Thus, there is a need in the art for a system which can address at least the aforementioned problems.

[0036] At step 202, a user of the vehicle 10 selects through the user device 102 one of the regenerative modes. At step 204, the user selects one of the regenerative modes from a low-level regenerative mode and a high-level regenerative mode.

[0046]

[0037] In an embodiment, in a non-limiting example, to control the intensity of regenerative braking, at step 212, a multiplying factor is applied to the maximum allowable charge current allowed to the battery 116 (for example, let us suppose, the allowable charge is of 40 amps). In high-level regenerative mode, the multiplying factor ranges from 0.8 to 1.0, allowing a charge current of 32 to 40 amps, providing strong regenerative braking ideal for stop-and-go traffic or hilly terrain. In default (normal) regenerative mode, the factor ranges from 0.5 to 0.7, resulting in a charge current of 20 to 28 amps, offering a balanced level of braking suitable for everyday driving. For low-level regenerative mode, the factor ranges from 0.1 to 0.4, limiting the charge current to 4 to 16 amps, resulting in gentle braking, which is useful for highway driving or when a more traditional braking feel is preferred.

[0047]

[0038] At step 214, in an embodiment, the set of predefined conditions includes throttle position sensor value being less than or equal to the predetermined value, vehicle speed being greater than a predetermined speed; and drive mode of the vehicle switched from the first mode to the second mode. In a non-limiting example, the throttle position sensor value being less than or equal to 10%, vehicle speed being greater than 10 kmph; and drive mode of the vehicle switched from the City to the ECO mode.

[0041] At step 220, in an alternate embodiment, when the regenerative mode is the high-level regenerative mode. The regenerative current limit is set to the first current limit being permitted by the battery 116 of the vehicle 10 for regeneration. In a nonlimiting example, the current limit is 30-40 amps. If the the set of predefined conditions are not satisfied then at step 222, regeneration will not happen.

[0051]

[0042] Figure 3 is the method depicting selectively operating regenerative braking in the vehicle, in accordance with an exemplary embodiment of the present invention.

[0052]

[0043] At step 302, a regenerative mode is selected by the user on the user device 102. At step 304, one or more vehicle parameters are received from the one or more sensors 112 by the one or more control units 110. At step 306, a regenerative current value is calculated by the one or more control units 110 by processing the selected regenerative mode and the one or more vehicle parameters. At step 308, the motor 108 operation is controlled by the one or more control units 110 based on the received regenerative current value when any one of a set of predefined conditions is satisfied as explained hereinabove.

[0053]

[0044] Advantageously, the present invention provides the ability to adjust regeneration levels through the user device. The rides of vehicle can now choose the desired regenerative mode setting which will suit their preferences or riding conditions. This will result in increasing comfort during riding experiences, particularly in situations where aggressive braking is undesirable or when maximizing energy recovery is necessary. The present invention enables rider to control the motor operation based on the calculated regenerative current value.

[0045] The selectable regeneration feature in a vehicle offers users the ability to tailor their riding experience to their preferences and needs. By allowing drivers to choose from different levels of regenerative braking, this feature enhances control and comfort on the road. Whether riders prefer a gentler braking experience similar to traditional brakes or a stronger regenerative braking effect for maximum energy recapture, selectable regeneration caters to a wide range of driving styles. Moreover, this customization extends beyond individual preferences, contributing to increased efficiency and reduced wear on mechanical brakes. By optimizing energy recovery during deceleration and braking, selectable regeneration helps maximize the vehicle's range.

[0054]

[0046] Thus, the present invention enables customisation of regenerative braking. Selectable regeneration not only enhances the riding experience but also contributes to overall vehicle efficiency and sustainability. By empowering users to adjust the regeneration level based on their preferences, this feature promotes greater control and comfort during deceleration and braking. Additionally, the ability to customize regeneration levels enables drivers to optimize energy capture and storage, thereby extending the vehicle's range on a single charge. With selectable regeneration, riders can strike a balance between braking efficiency, comfort, and environmental responsibility, making it a valuable feature for modern vehicles striving for optimal performance and sustainability.
